We booked a 'King Guestroom' and ended up in a disastrous room.
The room was actually really tiny, you couldn't even properly open two suitcases, and on 5th floor in the East Tower gave a lacklustre view of the entrance parkway instead of promised "City/Bayview". But what made it really disastrous was that when we returned home at 1.30am, our room was a *ç%&ing discotheque with the bass of the club downstairs booming through the walls.
But I have to say - and that's why I still award four points - that they really tried to make up for it. We received an upgrade - and that was what made the stay enjoyable. So I would strongly advise to go for nothing below "Deluxe". Not sure what category we were assigned in the end, but it was bigger, had a table with a little bench, was in the other building, and had partial ocean view.
Room maintenance twice a day, free wifi without any password nonsense, iPod docking station, huge TV, very attentive reception and pool bar/restaurant service, and the excellent beach club with super obliging service and the little box with water and fruit make it way beyond average. And an extra point for check-out at 2pm. Outstanding!
The crowd is mixed with quite a surprising share of families, however has a slight tendency to being boorish, but I guess that's natural in Miami Beach.
Service was extremely courteous. They advised us to park literally around the corner in the public parking ($16) instead of using their valet garage ($49), made us feel very welcome, and as mentioned really went the extra mile to make our stay enjoyable after the initial room disaster. They told me in the meantime that they'll work on the soundproofing, but for the moment I would advise to stay way off lower floors on the East Tower and the 'King Guestrooms' in general.
Could work on the room service as twice items ordered didn't arrive even after 30 minutes so that I eventually rather went down to the reception to pick it up. But maybe they just had a bad day. Not having a sufficient supply of newspaper is actually not acceptable for a hotel of this standard and price.
