Hello....I have never stayed at either, but I usually do an internet check of images and reviews before making reservations at a new location. In looking at those two, on Trip advisor, Owls Landing had enough low star ratings that I would not choose it...the photos didn't look very good either....Ames Brook sounded the best of the two.
You didn't, although, say when you are planning your trip...both are closed for the season, but maybe you mentioned your plans in another post that I missed.
Sounds like a nice road trip, though. My husband and I went from Maryland to Ontario in a camper and New England is awesome.
