I've been to Calica. Its just a working dock. You can catch a cab to Playa del Carmen which is a wonderful little city with Senor Frogs, lots of shopping and a great little beach. You can also go to Xcaret which is a very nice eco-park. You can swim with the dolphins there. Cab only costs $10.
Life is too short to let the ship of your dreams sail without you.
