What to do for my 30th Birthday?

My next birthday is my 30th and I would like to do something fun and maybe a little exotic. However I am not sure what to do. I am asking ahead in case I need to save bigger bucks.

Here are the things I feel that you need to know to try and get the kind of suggestions I am looking for:

I have very few friends and the ones I do have don’t have spare cash so traveling with people or anything that costs more then dinner is out at least with my friends, but this is not for them it's for me. When I say a few I mean like three so big parties are out too. I am not a girlie girl so manicures, spas and stuff like that are also out, and not to mention I don't like strangers touching me so anything that is hands on is eewww. I do love excitement, anything fast or maybe with a hint of danger is cool. But at the same time I don't drive so if I can't take a charter or a cab to it, it probably won't work. However this is where excursions come in, if I can gain access to the fun via a resort it might work. More then likely I will be alone so safety is also a concern. Also I do not like children of any sort so I would prefer that kids either be excluded or limited. I consider myself NC-17 so I am sure parents don't want me around their kids anymore then I want to be around them.

I have been to Vegas so many times that it’s no longer fun and while I don’t mind gambling a bit, that to be the focus of the trip is just sad.

I know that I gave limitations but I am hoping there is some single people out there that have had this issue and still managed to have a great time.

I am looking for adults to answer so if you still are being provided for by your parents please don’t bother answering.

Thank you!!
