I went to Fun Spot a few days ago (7/25) for my little sister's brithday. It was more of a spontaneous thing than a planned out trip, but I did come up with some tips for you guys for when we go. The previous post has a written list of things to bring.
1. Be prepared for it to be very hot.
If you buy a fun spot souvenir cup you can get free refills all of 2017. If three of you get cups at the same time you get a discount.
Bring sunscreen, a mini portable fan, and sunglasses.
You can either buy food there, go to a restaurant nearby, or bring your own food. If you bring your own food they won't let you bring it in so make sure it's something that won't go bad in the car because you'll have to go out to the car and eat it.
Here is a link to a page showing nearby restaurants:
3. Ticket options
