Hi! I would agree Universal would be your closest and best bet for a fitness center. I grew up in Leola and it's much more rural than Long Island and you will probably have to drive a bit further to things here, than in LI. Conestoga Valley is a decent school district, although not the richest in the county and probably one of the smaller ones. there is also Lancaster Catholic if you would choose to send your kids to a private school.
the pace is definetely slower here than Long Island, if that's what you want. I"m a stay at home mom too (mostly) and I have found enough to do with kind neighbors and friends and programs for toddlers etc at nearby churches and libraries.
hope that helps
