Is folding correct here?

[Munchkin Mayor]

15-30 game at CP. Typical game there with some TAGs and some gamey fish.

UTG+1 is a donater. His card protector is a plastic bison. He raises. Another guy who doesn't matter calls. Button calls. Hero in SB completes with K [img]/images/graemlins/club.gif[/img]Q [img]/images/graemlins/club.gif[/img].
Villian (solid aggressive player) in the BB three bets. Everybody calls.

15 small bets to the flop.

Flop is A [img]/images/graemlins/heart.gif[/img]K [img]/images/graemlins/heart.gif[/img]8 [img]/images/graemlins/club.gif[/img].

Villian bets out. UTG+1 calls. Another caller. Hero peels.

19 small bets to the turn.

Turn is 4 [img]/images/graemlins/club.gif[/img].

Villian bets out. UTG+1 raises. Fold. Hero looks to his left at Villian, sees Villian has lots of chips in his hand. Looks like he is getting ready to 3 town it.

What should Hero do?

BTW, no personal attacks. I am NOT Hero in this post.
