GSC everything we wanted to do is booked, will more become available

My husband and a couple of my sons wanted to go jet skiing and parasailing however there is only single seating jet skiing and we needed 2 seater due to the boys ages 14,11 & 8 and parasailing is only available at 8.30am which is to early for me to get them all dressed and be off the boat in time.

Does anyone know if they release more times or does that mean it's sold out. Only the cabanas are sold out already has well.

There will probably be some "walk-up" slots....that's really all you can do, if you don't want to guarantee slots at 8:30....

Actually, swim trunks and a t-shirt is all they need!!!

I know they keep some dining reservations back for onboard booking, so it would make sense that they'd do the same with GSC activities. I know you can only book clamshells on board.

I'd suggest checking myNCL regularly in case someone else cancels, then go straight to the shore excursion desk when you board to see what's available.
