Interesting, @Dutchboy - my experience was different. They suggested the same price both ways. Also, last summer we had airbeds, old blankets, and not a private bath. Now we have real beds, nice linens, and a private bath - but the price tip has remained the dame.
Yep, I just checked it again. I changed from 'private room' with one bedroom to 'entire place' with two bedrooms (which is what I have) and the price tip stayed at $70 - when hotels are going for $200+
