Arrived at the Lumen 06:00 am after an overnight from Hawaii, greeted warmly by desk staff, quick check-in and were informed that we could go to our room immediately! Free coffee/tea/etc were available in the foyer so we had a drink first and headed off for a couple of hours snooze. The room didn't have any windows and the beds were soft, perfect for anyone jetlagged. Covering some of the other points raised by reviewers..the room was large, plug sockets available at desk level, sliding door separating loo/shower from bedroom which were self contained anyway so no issues there. Having no windows was interesting but as we were only there for two days and didn't want to be on Dallas time anyway it didn't really matter. Had breakfast in the restaurant, good quality and reasonably priced.
Nothing to do with the hotel but don't arrive at DFW terminal A at 04:30 a.m. no food or drinks, no taxis and nobody on hand who could help with anything. Eventually rescued by a passing DFW Service guy in a car who took pity on us and phoned for a taxi. Really bad experience.
