Book Early:-)
You are taking a chance by waiting....but then again it depends on what you want to do...some of the excursions have unlimited openings, but the popular ones usually have a certain number of openings....I always book with the ship, it's a little more expensive, but I know they've reseached the vendor and the ship won't leave without you if something makes you late back to the ship...Happy Sailing...
