ELI5: What's the difference between a hotel, motel, resort and inn?
gpt
They are general categories that hopefully convey what one can expect from the establishment.

A hotel would have full features, including indoor hallways, room service, laundary, and maid service (to name a few examples).  

The word motel derives from "motor" and "hotel" and were originally meant as a place for motorists to stop while driving places.  They have sparser amenities and rooms that often open onto the parking lot.

An Inn is meant to connote a more traditional, less corporate, but small-ish accommodation.  Often an inn is in a setting that is itself a destination (unlike a motel) but doesn't offer the services or luxuries of a hotel.

Anything that calls itself a resort is doing so because it wants to convey that you can enjoy your vacation largely at the resort itself.  So you would expect it to have a pool, nice views, and other activities on or adjacent to the location.
