I know what you mean! The same thing happened to me on my 30th. We were planning a group trip for my birthday and we were going to rent the entire villa at Villas Sur Mer for all 8 of us, which back en was a pretty great deal (the villa is now the big house but that was all that was there back then). I was so excited. But everyone else was seriously dragging their feet, when the time finally came it ended up just being me and my boyfriend and we stayed at the Penthouse at Blue Cave Castle, which was still unbelievably awesome and special, but to this day I have still never stayed at Villas Sur Mer like I had wanted to and that is also when I learned I will no longer let my plans revolve around others doing or not doing something.....it usually just causes more frustration than necessary. If the owner is friendly, maybe he will work with you on something. Or maybe you could find others who are interested in staying wi you....I bet that would make the current group either get in gear or bail out. Or you could just tell them the current situation and let them know it's either now or never. I wish you the best of luck.....but just know this, no matter which way it goes, you will have a great birthday because you will be in Negril!
