Grand Caymen is just an hour flight from Miami. It's a perfect long weekend island getaway destination. The people are incredibly nice. The weather is always great. You might get some afternoon showers, but they blow out as quick as they come in.
See the Turtle Farm, send a post card from Hell, check out the Botanical Gardens and the Butterfly Farm. DO NOT MISS Stingray City. You can explore the Pirate Caves, visit Pedros Castle, Rum Point and numerous gift shops. Don't forget to pick up some famous original Tortuga or Blackbeards Rum Cakes.
Quick Tips:
If you want to go for peace and quiet and avoid the crowds as much as possible, do your research in advance and go when there are less to no cruise ships in port. I was there from a Friday till Tuesday and the only day there were ships in port was Tuesday. Two ships arrived in along with about 5000-7000 people. The other days, it felt like I had the island to myself. It was wonderful.
I recommend taking a snorkel trip to Stingray City with Captain Marvin. We stopped twice for snorkeling and then stopped at the sand bar to pet and "swim" with the rays. The cost was about , very reasonable for a four hour trip. The swim/snorkel guide was very informative. When we got to the sand bard, we each got out pictures holding the stingrays and we were told to kiss it on the forehead between the eyes. By doing this we would have several years of good luck. Okay, those rays taste weird and kinda slimy and salty. I was a little nervous at first as I did this just after Steve Irwins accident but these rays as so used to people, they are so gentle and incredibly friendly. They love rubbing up against you. It was very exciting and fun.

Best Way To Get Around:
To get around the island, it is less expensive to rent a car than to taxi around. It cost about oneway to get from Seven Mile Beach to George Town where all the shopping is, by taxi. Go to Andys to rent a car, they have great rates. They are located in Seven Mile Beach across from the Marriott. You can rent a car for about per 24h period. And by renting a car, you have the freedom to explore the island at your pace. In one day you can visit the North Shore, George Town, the Botanical Gardens, Hell, and much more. Andys will pick you up and drop you off for free. For those not used to it, they do drive on the left side of the road. Don't be afraid, it's very easy to get used to.
