I just checked, our Holiday Inn here is 0.10€ per night cheaper on Expedia. That wouldn’t even trigger their best price guarantee (1% saving needed). But yeah, that is not worth it, I haven’t actually booked a hotel in a few years, so I guess things changed for the better.

edit: Of course, Expedia doesn’t even have Motel One which is a nice 50€ cheaper than the Holiday Inn, and that’s for their 2nd cheapest room.

edit2: Okay, actually this is pretty confusing. Apparently, Motel One website and Expedia have 2 completely separate contingents of available rooms. Some days I can get the cheapest room at Expedia with no rooms free at the M1 website, some days they don’t have any rooms while the medium room is available directly.
