Last year we stayed at a fairly new hotel with a park & fly package--the Hilton Garden Inn. I believe it was roughly $130 (parking included for 10 nights + 2 nights paid @ $5 p/night). That's a fairly good deal when you figure in what parking is going to cost. The hotel is very nice--great complimentary cookies

and was quiet. While it's off the beaten path (.5 of a mile off Merriman), it's a scant 10 min ride to the airport.
We have also stayed at the Courtyard by Marriott and it was fairly nice as well. There is a manager's (or was the last time we stayed) reception each evening and the pool area is cozy and clean. There is a Bob Evans very near by as well. As I recall, the rate was also a park & fly (8 nights) and ran us about the same as the Hilton Garden, $130 w/less days free parking.
The former Fairfield n/k/a Ramada, I believe--could be wrong on that one--was typical--lower priced (many years ago and again a P&F pkg running around $80). The pool is an outdoor pool at this hotel and the rooms were really small.
On our return trip last year we stayed at the Clarion ($71 p/night) and it was in deplorable condition. The carpets were so worn the wrinkles looked like elephant skin and I nearly fell walking. The lobby area was nice, but that was the only thing about this place that was nice! We should have spent the extra $30 and stayed at the Hilton where we began our trip.
Frankly, that's the only hotel I would never recommend. I wrote to HQ about this hotel and all we received in response was--thanks, we'll pass it on.
Many years ago we stayed at the Super 8 and it was tolerable. I don't think I'd stay again though.
There are a number of places around the aiport that are barely tolerable. I'd look into the park & fly packages which, when viewed as a whole, are a pretty good deal.
Good luck--I've got to locate our overnight for June as well. LaQuinta had some nice rates last year, but the Hilton was a pretty sweet location, clean, comfortable, and not quite as noisy as others in which we've stayed. I'll be considering my options soon!
