I booked excursions, a spa appointment and Palo brunch online. If my son suddenly get sick on the ship or refused to utilize the kids clubs, how far in advance do I have to cancel those activities? I booked Palo brunch on the last day at see before we get back to LA. Fingers crossed he at least goes during that time! My son is seriously shy, not a joiner, does not really like crowds of other kids, needs time to get used to new situations, has some mild sensory issues, etc.so I'm prepared to cancel if he won't go.
