She meant "outside entry"

I believe she meant "outside entry" - most motels are basically outside entry. Motel6 is among the cheapest chains (Super8, Econo Lodge, etc, of course it is no good. For motel type lodging, Hampton Inn, Comfort Inn/ Suites, Fairfield, Courtyard, etc would be 3 times better than Motel6 type, eventhough they, too, can be "outside entry" and can see your car from your room.

Personally I would use priceline on all the places she visited, except Las Vegas. Actually sometimes one can get Venetian for $79 to $99 on Priceline, but most of time one can get decent deals on LV hotels own websites for midweek stays.
