Spendthrift is a great location, but might be a bit noisy a lot of the time,,, Others may enlighten you about the rooms. Everything (including bug repellent) is more expensive on the island as everything has to be imported. I like the little towelettes as they are handy to carry around. The drinking laws are fairly relaxed, so you will be fine carrying your drink to the next bar or around the town square.
My advice is to stay aware of your surroundings and do not trust everyone you meet (sounds crazy, but I see it happen all the time). Like everywhere else, times are hard here and there are opportunists lurking.
Come to Karaoke on Tuesday at Fido's, Wednesday at RoadKill or Friday at Playa Lounge - we would love to buy you a beer
Above all else, enjoy your well earned vacation!
