Welcome aboard, Kaede! With just a few months left until your family sets sail on the Disney Fantasy, you must be getting pretty excited to head south for this magical winter cruise!
You mentioned surf lessons while sailing on the Fantasy, so I'm guessing that you're looking into the
Surfs Up! Surfing Adventure in San Juan, Puerto Rico. What a fun way to spend the day on that island! This has become a pretty popular adventure, and it may be that the reason you can only view one time for surfers and a different time on the
Surfs Up! Observer Adventure is that the surfers spots are sold out for the 8:30 time, and the observers are sold out for the 12:45 slot. I'd suggest you give the agents at Disney Cruise Line a call at 800-951-3532 to see what further information they can give you when they look at that exact date and it's Port Adventure availability. If you find you can't coordinate, keep checking back, as guests may cancel before you set sail. Again, onboard the Fantasy, stop by the Port Adventures desk to see if you might be able to add those adventures at the same time. Of course, it's always best to book ahead of time since adventures do sell out, but I understand that in this situation, you can't really book one without the other, so keep checking back! Availabilities for Port Adventures can change, especially as you get closer to your cruise and other guests change their plans for adventures.
I hope you're able to coordinate times so that you can all attend! Have fun planning, Kaede!
