The way this is sometimes done is by using the "Owner" reservation type for the long-term or seasonal reservation, and then use a a "Normal" or "Free Stay" reservation type on top of that (for the same person) when they're actually on site. If you prefer it to be called something other than Free Stay, you can add a new Reservation Type (in the Pick Lists) -- just make sure the Base Type is still Free Stay (you can't add base types).
If you don't want to use the Owner reservation type (because it does leave the site "available" for bookings even through the name is shown on the site), another alternative would be to add them as a a Guest reservation, which again would be on top of the existing seasonal or long-term reservation. However if you're wantingstatistics of when they're here, it's still a good idea to use a spacial reservation type for the seasonals so you can count them separately from the short-term stays.
