I went there too in July and I had the time of my life! I didn't want to leave.
Here's a link to my pics:

I went on US Airways from Philly and we stayed for about 8 days as well. I went to the disco almost every night and there was a bar called the Coco, which I was invited to by a couple of the guys that work in the World Cafe. I went and danced the night away there on the last night.
One guy I have been able to keep in touch with, you probably saw him--he makes Omelettes in the World Cafe. I love this place and I'm going back really soon. Glad you guys had a good time too. Next time I go, I'm going to see more of the country--this time I mostly stayed on the resort.
