I stayed at the Holiday Inn on Electronics Pkwy for our last trip as well, I think the price was the same as Siobhan's.
Prior to that we stayed (twice) at the Best Western Airport Inn, and one other place, I think it was Candlewood Suites. We really liked the BW, because it is literally on the edge of the airport so it takes about 2 mins to get there in the shuttle (and their bar has awesome chicken wings!) but they were about $35 more than the Holiday Inn this last trip, and their rate only includes 7 days parking while HI is up to 21 days (we were staying 10 days).
I would choose either one again, they were fine. HI is very close to a little mini mall (just walked through the parking lot and across the street).Had a convenience store, drug store, etc which was great as the kids wanted a snack when we arrived and I had forgotten a couple of items so we were able to get drinks, etc.
