Funny...at first I thought you were my mother :-) She loves diet coke while my wife and I love Pepsi products. I don't think you are going to be in any luck finding a coke product though. The only offering for the mini-bar was Pepsi and in the restaurants that is all they served. I don't recall seeing anything in the dis & dat store either. You may be able to head further down the beach to find your fix.....of Diet Coke that is :-)
You won't find Diet Coke in Jamaica at all. They have Coke Lite - which I love! One of my favorite parts about going to Europe or Jamaica is getting a Coke Lite which is different from Diet Coke - I think it is better but I suppose its a matter of personal preference. Anyway that said we had Coke Lite stocked in our minibar every day no problem.
CSA has Pepsi products, I believe it varies by resorts. The soda pop tastes different in Jamaica than in the U.S. and Canada. They use different ratios and different sweeteners. You can buy Coke products at the market across the street from CSA (if that is where you are going). But it will taste different than at home.
You can bring a liter of liquor each (duty free) with you to Jamaica. However, you will have to pack it in your checked luggage, because you can't bring that much liquid through security. If you have a connecting flight, you can buy duty free liquor at your connecting airport and carry it on the plane. We did that last year in Charlotte enroute to Grand Cayman. The Duty Free shops at the airport don't have a very exotic selection, so you may be out of luck on your particular choice of liquor unless you risk packing it in your checked luggage.
Will Coca Cola Light work? I just checked the pic I took of the mini-bar in our suite at CSS. And yes, you can pack the soda and rum in your checked bag, but be careful. I encountered difficulty with my packed liquids exploding in my bag on the way home. Good thing I had them in a plastic bag.
How are you guys getting other things stocked in your minibars? The only thing in ours that I wanted was water and the cranberry juice cans so I asked if I could get extras of those instead of the beer and liquor and they said no, they do not allow substitutions. You only get two tiny cans of cranberry a day.
We had a similar problem as Melody. We had 2 bottles of Ting each of the first 2 days (out of 9) and then no more. I left notes requesting it every day with no luck. Now, as far as I know, Ting is a standard stock item for the mini fridge. I don't think I was making a special request, I was just asking for what was in the fridge the first 2 days.
I've read elsewhere on this board about people who have made requests such as Rum Cream and got them put in their rooms. I guess it all depends on who's doing the stocking of your room. I know I was more than disappointed all of the days we got back to the room to get ready for dinner and, once again, no Ting.
