My husband and I are going on our first cruise this June. We are going on Carnival Dream to Cozumel, Belize City, Roatan, and Costa Maya. We are a young couple who spent all our money on the cruise, so we were wondering what to do at the ports. We would like to just kick back at the beach and shop and some places and maybe do 1 or 2 excursion type things. What would you suggest to be the best places to do an excursion, shop and hang at the beach??? Thanks for the help!
