When we stayed at the Sheraton the night before out first PG trip, we went up to our room to check it out and thought a nice tropical drink sounded good. So we went down to the pool area bar and when we finally got someones attention, we ordered two mai tai's. They were pretty normal size, certainly not the drink of the day in a souvenir cup. The bill was a stunning $27! It was Hinano for us after that for a more reasonable $4.50 or so. The beer from the inroom bar was the same price as the regular bars, by the way, so if you are going to have beers you might as well start there.
