I had what they called a suite without doors last summer. Usually I hate this kind of suite but this one was huge and wonderful. I was also alone so didn't need to worry about others which maybe would've made it less wonderful.

But I'd be happy to stay in it again and use a TSU. Normally I won't use a TSU or even go back to a hotel where the suites don't have doors.

Here and HR Churchill are probably the only exceptions to this rule.
