Agree with you that that price is steep, but not out of line for anyplace close to a resort. Comfort, style and convenience are at a premium. The resort I frequent, Boyne's rooms are great, but run $200+ a night at peak! I can't afford that so,...
The cheapie Best Western I usually stay at in N. MI. is $120 a night during peak season. (...I get a Rewards mmbr Internet rate for around $75!)
But it's still only your standard non luxury BW. I have learned to take a few things with me to make the stay more tolerable.
I hate noisy rooms and can't sleep if heaters growling or unruly kids running the halls. I bring earplugs! I also bring my own pillow. AND those nasal strips. (... electric heat and that cheap hotel disinfectant aggravates, dries out and plugs my sinuses. With those things, I can breath normally!)
I take a cooler with snacks, drinks, etc. and since I'm a coffee snob, I bring an electric kettle, good fresh ground coffee and my french press! Need my morning "mana!"
All of that helps a cheap room becomes a comfortable bargain!
