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 no spare cash so traveling with people is out. 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!!
