Waldorf is also a Hilton brand. So it’s mainly all Hilton brands and a few others, but no Marriott.
Time to drop some knowledge from my time working in the hotel industry.
Disney on-property hotels serve leisure travelers/families. Almost exclusively. They do not have the large on-site meeting facilities or conference centers or other amenities needed to cater to business travelers.
Hilton, meanwhile, caters primarily to business travelers, and roughly all of their Disney area hotels are conference hotels, including the Hilton Orlando Bonner Springs, which is in the process of being converted into Hilton’s first-ever Signia Brand hotel, which is SOLELY for conferences/business professionals.
Orlando is the #1 conference and event city in the US, and those conferences need to partner with hotels that a) is capable of producing large events servings tens of thousands of guests at a time and b) is bookable by most corporate travel policies. Most large companies have an existing business contract with Hilton, that gets their employees contracted rates. Disney doesn’t do this.
Here’s the other part of this. The REASON Orlando is the #1 events city is because the conference-attending parent can get their travel and hotel covered by work, bring the spouse and family, and the non-conference attending family can take the kids to Disney during the day making it a cheaper vacation. Generally, these conferences offer these as packages, so that they can buy a reduced ticket price for conference attendees. Disney wants this business - it translates to tens of millions of visitors to their parks each year. But they need a hotel partner who can facilitate these large trade shows and conferences to make it happen. They essentially have two choices in that: either Marriott or Hilton. They have to pick at least one, and it looks like this year, Hilton is the winner. (And if I had to guess, they’re actually still negotiating with Marriott and making this announcement that excludes Marriott will help put the squeeze on them to agree to a deal sooner rather than later…)
One other thing - frequent business travelers/executives generally have a LOT of hotel points. And so they want a place when they do travel for leisure where they can redeem those points. I can pretty much guarantee you that someone in Disney’s data science department has run the numbers and figured out that the spend per trip amount for guests who redeem points for their lodging in the DS Hilton hotels, and figured out that while these folks aren’t spending on a Disney room, they are shelling out plenty in terms of vip tours, enchanting extras, hopper ticket add ons, costly meals, etc. So they’ve decided it’s worth it from a price perspective to give them this perk, because otherwise these happy-to-spend travelers will use their points to go vacation elsewhere that will allow them to redeem points, and Disney misses out on all that revenue.
So you may not like it, but it’s all very logical as to why Disney would do this.
