We've used Best Friends a couple of times, once for an overnight and once for daycare - both while staying at Fort Wilderness with our RV, so not long-term like a week, but we really liked it.
The facility is clean and bright and the staff was always friendly and helpful.
During one of the visits my guy wasn't enjoying the group playtime that we had signed him up for so they called me and asked if we'd like to switch it to one on one play time with a staff member, to me that spoke volumes about how they watch the dogs, and their willingness to be honest with the owners.
