There are timeshare properties all over the world that people are desperately trying to get out from under, and those people rent them out to pay the fees until they do. There is no way that I would actually buy a contract when it is so easy to rent someone else's financial folly and only pay for the stay. The key is that you must be willing to clean when you travel; if you don't want to do that, then time-shares and short-term rentals in general are usually not for you.
That said, the one big worldwide chain exception to that rule that I know about is a company called Sonder, whose units are fully serviced. (They still do not have restaurants on-property, though; if you want someone to bring you prepared food, you have to use a delivery service). They started out serving traveling executives doing temporary assignments, but have expanded into more touristy areas in many major cities. Not all of their properties have spaces with 2 full bedrooms, but those that do are clearly marked once you are given a selection of properties to look through (and yes, the easiest way to quickly filter for them is to enter a minimum of 5 guests, though sometimes that will snag a room with 2 Queen beds and a sofabed.) They tend to be popular with female travelers, especially, because their security is very conspicuous and tight. Ironically, most of the properties they offer in the Orlando area are NOT big suites, because their primary market is still executives, and in Orlando those clients tend to like to stay near downtown, not the main tourist corridor.

I like Homewood Suites (Hilton) and Staybridge Suites (IHG), and each property does have at least one full 2-bedroom suite, but often there is only one in the property, so booking them for a stay at a popular time can be tricky.
BTW, with regard to Residence Inns, the buildings that have the separated bedrooms and fireplaces tend to be their older properties, mostly built about 40-50 years ago. (They look like typical suburban "garden" apartment complexes with separate buildings that have a lot of outside stairways leading to the 2nd floor units.) The newer properties in the chain have interior corridors and have gone more to the one-bedroom + sofa-bed in the living-room style (though each property has some 2 bedrooms, and even a 3-bdr sometimes), and they also mostly have eliminated the fireplaces.
