I stayed at the Dalano during a work trip for a convention at the Mandalay Bay Convention Center. My room, which was a "standard" room, had a sitting room with a work desk and a half-bath and also a sleeping room with a separate full bath. Both rooms had floor to ceiling windows and there were TVs in both rooms and in the full bath.
The bath had a shower and a big soaking tub which I enjoyed using after a long day on my feet. I had two minor problems with my room, one, a broken clock radio, was not fixed until I reported it a second time. The more serious issue (the water in the shower was so hot it was scorching and there was no way to make it cooler) was fixed before I returned to the room.
The staff was helpful and friendly and assisted me in obtaining tickets to see "O" at the Bellagio. I thoroughly enjoyed my stay at the Delano and would stay here again if I have the opportunity.
