We are on the Magic 4 night sailing 3/19/13. This is our first cruise, traveling with hubby and 3 kids ages 9, 7 and 4. Our only port is on 3/21 in Cozumel. I was planning on doing Paradise Beach but I'm second guessing based on the fact that there will be 4 other ships in port that day. Carnival Paradise, Celebrity Constellation, Crown Princess and Oasis of the Seas. I am looking for relaxing on the beach, good food (we don't drink so that is not a consideration) and something to entertain the kids. Nothing too structured, expensive and no long travel times. Experienced cruisers please advise. Thanks for your help.
