Grand Cayman and Ochos Rios shore tours

Hi!
We leave on Dec. 13 and want to know if anyone has any specific tours that they think are especially good at either one of these ports. I would also like to know the prices if anyone knows. We are most interested in a little shopping and seeing things that we normally wouldn't be able to see. We are also a little budget considerate. Is it easy to get lost? Could we find our way to Margaritaville after one of our tours or find our way to shop? We are looking for any opinions we can get. Are any drinks included in the Party Boat tour?
We were looking at the See and Sea Island Tour at Grand Cayman and the Jamaica Queen Party Boat and Dunn's Falls tour, anyone have any opinions about them or know how much they cost per person?
Thanks!!!!

I am leaving on sunday and going to Grand Cayman, Cozumel, and Ocho Rios.
If you go to Carnival's website you can find tours. This is what we are doing in Grand Cayman and Jamaica:
Grand Cayman we are taking the Stingray City and Island tour-cost $49.00 pp:

On arrival to the cruise ship dock you will be met by tour guides, who will be in charge of directing you to the awaiting tour buses. Experienced drivers will give a detailed presentation of the different land based sites you will be visiting, as well as other popular attractions along the beach, including the Cayman Island Turtle Farm and the famous town of "Hell". After the last stop, guests will be driven to the marina for a trip to Stingray City. Once aboard the boat a safety and tour orientation will be given and everyone will be fitted with the necessary snorkel equipment and life vests. Fish food is provided for the stingrays. Approximately 45 minutes for snorkeling. After departing Stingray City, complimentary rum punch and fruit punch will be served. Upon returning to the marina, guests will board the buses, which will return them to the cruise ship dock. Approximately 3 ½ hours

In Jamaica we are doing the Highlight Tour A--$49.00 pp

Begin with a visit to the best duty free shopping area in Ocho Rios. From there it is off to the Shaw Park Gardens. Enjoy these beautiful botanical gardens that overlook the picturesque Bay of Ocho Rios. Travel back down town to the coastline and Dunn's River Falls. Visit this magnificent 600-foot waterfall shaped like a giant staircase with the help of an experienced guide. Enjoy climbing the falls or choose to simply enjoy the incredible view and scenery. Note: Aqua shoes available for rent on board Approximately 4 hours
