Hampi will more than live up to your expectations, i did the trip 4 years ago and found it just amazing.
As to Hospet being wild, I really don't know what you mean, it's certainaly a good example of an Indian rural town. On the organised trips you are only there to eat and sleep. We went with Melo Tours and the Hotel was basic with indian shower (tap and jug) western loo, hot water 2hours morning and evening and room service boys on every floor! Alcohol was available in the restaurant.
I have heard that there are some strange characters hanging around Hampi but on the organised tour you will be fine.
my tips---
Lots of wet wipes for the train journey, the red dust gets everywhere
Sensible shoes, adventure sandles or the now popular Crocs.
Shorts mini skiirts or sun tops are not advisable
I found a calf length skirt was especially good , easiest if you need the loo !
A sarong is always useful
Remembering all this makes me want to return
Have a great trip
