Most 'suites' I read about are really just a typical hotel room, but with a fridge and microwave and maybe a 2 burner stove. That, imo, is misleading.
Advertising a 2 room suite isn't misleading. The OP somehow is thinking it means 2 bedrooms. As mentioned above, if I'm looking at houses, I'm not going to see 8 rooms in a listing and think it has 8 bedrooms.
Embassy Suites has always advertised their rooms as such, and I don't think anyone has found it misleading until now.
