We have done a mixture of Aires, municipal and commercial sites. This one at Chateau Eperviere has been our most expensive but our 11 year old is thrilled with the pools, basketball court and space to chill...and get free wifi .And they may only have 2 or 3 weeks, have children to entertain and restricted to peak season.
I would happily just use Aires but we need to meet everyone's needs otherwise it wouldn't work for us.
