Thoughts:
You are from another country, all countries seem to use different hotel terms whether type of lodging or type of bedding etc.
In USA I think traditionally a HOTEL had interior halls and MOTEL had their doors direct to outside.
BUT Disney doesn't want to be seen as a motel anywhere so they avoid the terms using "resort" instead. One reason may be is that motel's are traditionally much cheaper, considered less desirable and none of Disney's fall in to a motel price range.
A RESORT is more likely to have an array of amenities, entertainment, dining and recreation etc ... more of an all inclusive feel to it. Many of Disney "hotels" do provide this but some do not. It's a unique use of the word. Disney is just a different animal.
NOW if you are looking offsite then I would stick to the traditional Resort vs Non-Resort, Hotel vs Motel vs Condo style. Of course it becomes even more confusing when one location offers more than one style of room. Wyndham at DS has interior and exterior access rooms .... so it's a motel and hotel???
