For such a short stay, you can call Kutchers (if its mid-week, as I’m not sure what the minyan story is there). They have a full food plan (hechsher for 2010 is ok) or a room only rate which was in the paper last week for $99 / night.
Another option (if shabbos is in your plan) is the motel next door to Mountain Fruit. Not sure of the name, but its rare that they are booked solid, and from there you walk to minyan.
Colonies are really not an option for such a short stay, unless you go to a place where you know someone who is there for the summer.
