Hi mikell, welcome to the board!
Caribe is about 3 miles South of town. Huge beautiful beach and pool, lots of loungers and hammocks, and really great folks. No water taxi necessary at all since your South of the cut.
We have walked to town more then several times and we are nearin 50 and smokers with kids. lol If it is REALLY hot and no breeze, bring a water bottle (or a Belekin)and pace yourself, stop in at all the resorts on the beach on the way to town and have a drink. (thats a lot of fun to do anyway, you get to check everything out and meet new people too) CI also has a free shuttle which goes to town and back a couple times a day/night, not to mention free bikes as well. They have water tramps off the dock, free kayaks, and if you fish and don't bring your pole you can buy line, hooks, and bait, and fish right off the dock, and have the restaurant cook it up for you! YUMMMM We do sometimes get a golf cart because we want to visit friends who live all over the Island. You could also hire a cab to town for $5.00. And I'm sure you could hire a cab for a “tour” as well for maybe $15.00. (give or take) So ya really don't need a cart. Although I really think everyone should get one for at least one day and tool around on your own. It's an adventure and you get a better feel of the Island!
Nothing is so close to CI that you will be disturbed by partee people. (Unless you be a partee people as we sometimes are, then we start the partee and others join in
) There are private homes for a spell going North before you hit any resorts and directly South of Caribe is Sunset Beach Resort. (We have only seen maybe 1 group of folks there every time we go so no noise from there) After SBR there are more private homes. Check out the maps on this site they are pretty accurate. Gosh... can ya tell we really do love this place... laugh!
With only two people you could do either a mini suite or a 1 bedroom. We have stayed in a 1BR, a 3BR, and a 1BR attached to a mini and were pleased with all.
Last time I looked at their web site it had pixs of all the units, so check each one out. Also I suggest you e-mail Vicki at email@example.com and she can give you any additional info for your needs and wants. OH, OH, don't forget to e-mail them with your kitchen needs prior to arrival as well: ie stock your fridge with a smoked chicken from the Sausage Factory, and a case or two of Belekin. lol just to name two of our necessities. hehehe
Wherever you decide to go have a GREAT trip!
