OK, as with many things,we have things that can be called facts, such as types of Hotels/Motels/Lodging, and then the personal opinion, such as what is high end.
If you look at Lodging, you have standards that have been set by others, such as
AAA.
So the top are the 5 star Resorts, that means a very high level of items in the rooms, great service, and lot of amenities like Golf Courses, beaches, etc. Also high end restaurants on property.
Then you have the Full Service Hotels, as mentioned, designed for either business or luxury vacation, and includes all the special personal perks like Valet Parking, Room Service, etc. For business hotels, convention services including meeting rooms In the
Disneyland area, I can only come up with about 10.
Then you have the next level,which is called the Limited Service Hotels, and it has plenty of sub-catagories. This currently is the most popular level, as most "chains" will offer things that you have to pay for at a Full Service Hotel as part of the nightly fee, such as free breakfast, WiFi, etc. The Hotel owners like the fact they can cut back on labor in not staffing Valets, Bell Hops, Room Service, etc.
One very popular sub-category in the Disneyland area is the "Extended Stay/Apartment style" Hotel, in which you get the larger room (and sometimes suites), kitchen facilities including pots and pans, etc. But then there are different levels in that category, IMHO, the low end would be Extended Stay America, which to me is the Motel 6 version in the group, basic but clean and comes with the kitchen. Heck, even some of the same brand are different, for example the Residence Inns in the area. I like the old school RI on Clementine next to the AGW, it is a Condo Style facility with nice grounds. The other ones are the newer style of a high rise tower and interior corridors and the need to use an elevator. Both versions have pluses and minuses, and it is up to the specific person as to which they prefer.
And then you have the low end, which are Motels, and in that I mean a 1 to 3 story building (or set of buildings) without elevators, outdoor corridors, your car is parked in front/near your room, and everything is fairly basic, designed originally to be the low cost option.
Now, in Anaheim, the dynamic has changed, and it is due to location. When built, Motels was the "in thing" in the 50's and early 60"s (anyone remember the Stovall's Space Age Lodge...)

So in the 1950's, Walt Disney couldn't afford to buy anything else, as he maxed out his finances in opening Disneyland, and even sold rights to things like the Disneyland Hotel, so many folks bought up land near the park and built Motels (IMHO, a smart decision). But due to many factors including building permits,etc. The options is pretty much update/refresh the property, or tear it down and rebuild from scratch. The nearest Motels to Disneyland have pretty much decided to just update, due to the cost/benefit forecasts. And some owners have done a nicer job in upgrading than others. So some folks can say "High End Motels",meaning a very nice basic Motel, versus a run down version....
Everyone is different, and a written post doesn't show some info that a face to face conversation will offer. So one person might mean more as to value for the money, as in what you get for the nightly fee, while others think a place like the Great Wolf Lodge Resort with all its amenities is important (More Stuff, but not caring too much about the budget).
So all we can do is provide information,and let the OP decide what is best for them....
