At Ocho Rios they will rent you a beaten up old pair of water shoes for $5. Get a pair at Walmart before you go. Dunn's River Falls are great, but what you are doing is walking up a waterfall with huge worn down boulders as the stairs. You will get soaking wet and it is very slippery. It takes quite a while to get up there and a 'leader' shows you the way- all holding hands. When I saw it I knew I couldn't contemplate doing it and I am nowhere near that age...
We took the RCCL excursion over there- it was billed as a leisurely cruise with tropical punch, Calypso music.... yeah right. We were on a sort of tug boat, got a Dixie cup of warm punch and nothing else, except they pointed out where the cup for tips were.. You can get a taxi over and do your own thing much more cheaply. That goes for all the excursions really. The one thing you get with a cruise line sponsored excursion is that if you are delayed getting back they will wait for you. If you're out on your own, they will not.
Generally speaking Jamaica is more edgy than I like, a lot of pests asking you to buy weed, stuff like that, aggressive vendors, it wears on you after a while.
Labadee is an island paradise, it is a peninsula off the coast of Haiti. It is a beach day with BBQ and drinks. They have all the water toys. WE did the tour of the island by Jetski with a RCCL leader.
Cozumel - last time we did the Royal Swim with Dolphins- booked direct with Swim with Dolphins at Dolphin Discovery on Mexico and the Caribbean
its cheaper than the ship tour. We took a taxi to Chankanaab Park for $10 and spent a couple of hours there. It was an expensive day but so thrilling. If the ship does not make it into port ( weather) they will refund 90% to you. Cozumel is easy to get around, it is one two to four lane road all along the beach. From the pier into the town 'center' costs around $6. We usually eat at Pancho's Backyard, nice food, lovely atmosphere, Mariachi music playing and it has lots of little shady atria.
Have a look at the Cozumel Insider - Cozumel MX - Activities, Accomodations, Trip planning and so much more...
it has lots of things to appeal.
Sometimes we go to Margaritaville, it's not far from the pier.
One other time we went to Playa Mia beach resort, a private beach, pool, restaurant- there are several along the main road, Paradise Beach, Nachi Cocum- you can pay various rates to enter- all inclusive with drinks/food or other levels, for $5 you get a nice lounger with sun umbrella.
Georgetown, GC- I usually shop in town (jewelry) and eventually we end up at 7 mile beach. Lovely. Never taken an organised tour there.
