Wow Ernie - that does seem high, unless you are drinking most of it! Drinks were a little pricey.
We averaged $62 US for 2 of us. That includes all beverages.
BUT, we ate at out-of-the way places, cooked in our loft and on the grill (2 lbs fresh lobster $25 US was 2 meals & a snack), and mixed drinks for the pool and the start of excursions around town. We also drank our way down the beach to town several times. Our most expensive meal out was at Fido's. We also brought some dried snacks and nuts from home. I highly advise bringing your own snack foods. We did stop for ice cream in town though. Mmmm Mmmm Yummy.
We went prepared for more expensive and do not hold back when it comes to food/drink. You can easily run up a large tab from what I saw. Next trip we will probably spend more as there were several places we would like to go.
