You're going to an amusement park that also has a water park that you get free access to. You'll be there many hours. What do you wear (including on your feet)? What do you bring? Note they have lockers for rent: do you store everything in your locker besides your clothes?
And some TMI: Ladies: It's that time of the month and you really need to keep a tampon with you at all times. Making it back to the locker and then to the bathroom in time might not be an option. How do you tote this along?
