-- Yes, the Hotel Alfonso XIII, a Luxury Collection Hotel in Seville, Spain is a wonderful hotel. The location is unbeatable. Service was great. Thoroughly enjoyed our dinners at two of the hotel's restaurants and our breakfasts. Incredible stairway is a worth seeing. Used SNAs to upgrade to a small suite, which made it even better. Generous welcome gift in our suite. Might be the best 5-star hotel we've ever stayed at.
-- The list states that the JW Marriott Orlando Bonnet Creek Resort & Spa is not an official Walt Disney World hotel, but that it's located on Disney property. True that it's not official. False that it's on Disney property (although you drive onto and off of Disney property to get there). It also overstates just how close it is to the destinations on Disney property. You don't receive the on-site benefits that all Disney resorts and some on-site non-Disney properties provide to guests. (I have not stayed at this JW, but I've driven to it.)
-- I like that the list includes a Fairfield Inn. Not every good place to stay needs to be a 5-star hotel affiliated with a luxury brand.
-- The list does not lnclude any Marriott Vacation Clubs or other high-end timeshares. That's not surprising. These are not luxury hotels in the traditional sense. Then again, not everyone has the same definition of luxury. I consider a full kitchen, a private washer & dryer, and a spacious condo-like suite with one or more separate bedrooms to be true marks of luxury. Marriott's Ko Olina, Marriott's Newport Coast Villas, and other properties of this kind lack some the attributes of a 5-star hotel (certainly no twice daily housekeeping!), but I've voted with my wallet for the luxuries I appreciate.
