The amount of time you will spend each trip digging out, winterizing etc I would think just find a motel, in the EUP a motel can be found for $30 a night two people or less if you share it with three or more. The last place we stayed at was $54 a night with tax. A hot shower and warm room is nice to walk into after 12+ hours on the trail.
We also stayed at a two bedroom cabin on the Lake at $85 a night a little more cost but you can cook there and save on meals. A couple air mattress and split the cost 4 ways it a good deal.
