Season Pass Frequently asked Questions

When does Neptune Island Waterpark open for the season?

Neptune Island will open to the public on Sunday, May 19, 2019. 2018 & 2019 season pass holders will be admitted to Neptune Island on Saturday, May 18, 2019 for an exclusive Season Pass Holder Event. For a complete schedule and hours of operation, please visit our About the Park page.

Do you offer a family pass?

Neptune Island does not offer a family pass, but has included 3 Bring-a-Friend single use admission tickets with every season pass.

What are Bring-a-Friend tickets?

Bring-a-Friend tickets are three (3) single use admission tickets that season pass holders receive to use throughout the season. Your tickets are good for one use each and will be active once you receive your actual season pass. These entitlements are applied directly to your card and are redeemed at the Main Gate, so you can skip the line at the Admissions Office. Once you have used your three Bring-a-Friend tickets they cannot be redeemed again in the 2019 season.

I purchased my season pass online, how do I get my actual season pass?

Once you purchase your season pass online, please bring your confirmation ticket that should have been emailed to you to the Admissions Office at Neptune Island. Our Admissions Crew will take your picture for season pass verification and will issue your season pass card. You will receive a season pass card for every individual that you have purchased a season pass for. The individual must be present in order to receive their season pass.

Can someone else use my season pass?

Season pass cards may only be used by the season pass card holder that the card is registered to. Season passes may not be transferred from person to person. Use of a season pass by anyone other than the photographed account holder, or the violation of any park rules, will result in expulsion and/or revocation of your season pass without a refund.

How do I use my discounts associated with my season pass?

Season pass holder entitlements may only be issued in-person at this time. Please visit our Admissions Office for assistance with redeeming your discounts. Food & Beverage discounts can be applied directly to your order at The Galley, Low Tide Lucy’s or Shark Shack.

How long is my season pass valid?

All season passes are valid for the entire season. The 2019 season will begin Memorial Day and end on Labor Day. We will be open to the public for Opening Day on Sunday, May 19, 2019.

What is Early-Bird Entry?

Early-Bird Entry is an exclusive perk for our Neptune Island season pass holders. This allows season pass holders the opportunity to enter the park 15 minutes prior to the general public on Saturdays and holidays (Memorial Day, Independence Day & Labor Day) for a prime selection of seating. Early-Bird entry begins at 9:45 am.

Do you offer discounts on season passes?

Because our season passes have already been extremely discounted from their $150 value, we do not offer additional discounts on season passes. We do offer discounts on daily admission tickets for Military, EMS, Fire, Police and Senior Citizens (55+).

Do I need a season pass for my child that is ages 2 or under?

Guests who are ages 2 and under are admitted to Neptune Island for FREE with our Neptune Island swim diaper cover. Our swim diaper cover is a one-time purchase of $9.99 + tax and is reusable for the entire season. These diapers are unique in the fact that they go over your child's normal swim diaper.a The swim diaper cover will act as their ticket into the park and season pass will not be required for these guests. To purchase your Neptune Island swim diaper, please visit the Admission Office. Guests who do not wish to purchase a swim diaper cover, must purchase an admission ticket for those in their party ages 2 and under.

Who is considered an "In-City Resident"?

In-City residents are those who live INSIDE the city limits of Hartsville. Because this project is funded by the City of Hartsville, we can only extend In-City pricing to Hartsville residents who currently live inside the city limits. To determine if your address qualifies you for an In-City Resident discount, please use this map tool.

Will you sell out of season passes?

Neptune Island does have a set number of season pass cards for each season as these are pre-printed for the season. Season pass sales will cease once we have sold out of these cards. All season pass sales will end on July 31, 2019.

What if I was a season pass holder in 2018?

This is awesome! Our Crew is ecstatic to hear you are planning to be a season pass holder for our second season. If you were a season pass holder in 2018, then please hold onto your 2018 card and we can apply your 2019 season pass entitlements directly to your card from last year. You will still need to stop by the Admissions Office on your first visit to redeem this season’s pass entitlements.

What is Splash Cash and how does it work?

New for the 2019 season, season pass holders will be able to use their season pass card like a gift card throughout the park to purchase items. Splash cash is monetary dollars applied to your season pass card using cash, credit or debit cards at the Admissions Office. No more worrying about carrying cash or your debit card at the park! Splash Cash can be used at any of our kiosks in the park except for Neptune’s Patio. Splash Cash is non-refundable.

Is there a way to receive a refund for my season pass?

All ticket and season pass sales are non-refundable. Season passes are non-transferable.

What happens if I lose my season pass card?

Uh oh! We understand life happens. Simply visit our Admissions Office during your next visit and we will gladly replace your card for a small fee. There is a $10 replacement card fee.

How do I purchase a season pass as a gift?

Someone must be on the Nice List this year to be receiving a Neptune Island season pass as a gift! Simply type in their information when purchasing the season pass online. All they will need to redeem their pass at the park is the confirmation email and tickets from the ticket link within the email. Please email our Crew at guestservices@neptuneisland.com for additional assistance.
