Quail Roost is a nice place IMO. We've stayed a few times for 3 - 4 nights to visit friends who were staying at Quail Roost for "the season."
Lots of activities at the park - indoors: painting, photography, cards and other games - special event parties for holidays - outdoors: horseshoes and shuffleboard. I'm sure they have lots of other things to do and Crystal River is a fun town and as other people said there are plenty of things to do in the area.
The RV dealer across the street is owned by the same family. They had the part I needed when my water heater quit working.

Got a cooped-up feeling, gotta get out of town, got those Airstream campin' blues...
