We are going on this same itineray in April. I have been doing a lot of research. One of the best parts is the wonderful 4 relaxing days at sea. These ports will be completely different from those you may have experienced in the Eastern, Southern or Western Caribbean. Shopping will be very limited. Belize is still a Third World Country. They plan to keep the country as ecologically balanced as possible by detering mass building projects. Mayan ruins, the Belize Zoo, Cave Tubing and scuba or snorkeling off the 2nd. greatest barrier reef are some of the recommended things to do. Costa Rica offers tropical jungles and tours inland. Roads and even hotels are not what American's are acustomed to. Plan on tours to experience the best of these new destinations. There will be limited taxi's or rental vehicles for "on your own" type touring. Beaches are also limited and natural at these three ports. One of the facts I just learned last night, was to plan on having US $$'s instead of using credit cards or ATM withdrawals. Our dollars are readily acceptable, but there is limited ATM or credit card acceptance. Plan on bringing bottled water on shore with you and apply plenty of sunscreen and bug repellent. This is a very tropical jungle and Rain Forest part of Central America. Once you get a list of Carnival tours after she does start this itinerary in November, you may want to seriously narrow down your choices and be ready to pre-book tours when Carnival institutes this opportunity if they do next year.
