How many people are allowed on the cruise? We will be at CN from 12/20 - 12/24, but leave on the 24th. We only have one day to take the catamaran cruise (Monday) and we understand we can't reserve it until we arrive at CN. We really want to experience the cruise. Is there a way to ensure we can get on the cruise? Also, does the catamaran have bathrooms? Thanks in advance! Melissa
