Ho Jo definately offers this service, but I don't know how nice the hotel is. Their web site says yu can use their lot for up to 2 weeks, and they will even take you to the terminal. Pretty good deal I think.
My problem is I either need a suite with 3 beds or 2 rooms. Taking our teenage kids, one boy and 1 girl. Need seperate sleeping arrangements.
I also saw Embassy Suites has a deal that you can stay there and use long term parking for $89 per night. I am going to check this out further.
I'll let you know if more hotels come up.
