Im a single woman who is not into swinging, or gay but wants a fun filled vacation, is it common for single woman to there alone?

You would be fine.
Most single women seem to have a run of the house when they are there.
Just think.. ..you have the right to make all the choices that you want, do what you want, and have fun.
I would advise that you go over to www ..com and read some trip reports.

Respect,
