The hotels all have character meals I am unsure who the characters are now but you could give a call to find out. At Portofino they are at the Trattoria del Porto and its a dinner certain days only. At Hard Rock it would be at The Kitchen again dinner certain days and at Royal Pacific also dinner certain days at their Island Dining Room. In the past the characters were woody woodpecker scooby beetle bailey and a few others.
Confiscos offers a breakfast that is held at IOA not sure what days could be every day and no sure of the recent characters I do know spiderman is one.
