bali january

Hello all.
First time posting on this forum.
I would like to take my 3 children to Bail this january(mid range price)
and have no idea where to stay etc.The kids are 13,11 and 8.
I have heard all about the yobbo factor etc and don't particularly
want to be totally surrounded by them but still want to be reasonably
close to to Kuta but not too close if you know what I mean.
Any ideas on what to do,where to go etc to get a little bit of culture
without boring the kids would be appreciated.

Thanks in anticipation
