Well, I'm in the Marriott Riyadh and while not exactly knocking my socks off, it is still a nice enough hotel - and I would come back here again, if I had to comeback here again, if you see what I mean.

I'm in a standard room - and it appears to be about 25 sq. m and is furnished with a very comfortable king bed, two winged chairs, a work desk with high speed internet, modest TV (which isn't a problem, cos there's nothing on but guys with beards, CNN and BBC World). Th bathroom is spotlessly clean and of a good size. Room safe, ironing board and bottle of complimentary water daily. mini-bar, reasonably priced, but not containing anything interesting - chocolate, water, juices gum and cigarettes. Decor is a bit 1990s, or American style - depending on your perspective - clean, well maintained, but about to be tired, but not quite yet. There are two executive floors and a lounge. Haven't been up. A local English paper is hung on my door each morning.
Room: 7.5/10

Reception is inside the main door, past all the scurity, barriers, and x-ray machines. Check-in was efficient (at 3am, mind) and the bags were in our rooms before we were. The lobby is a large open atrium containing the 6 floors of the hotel, with balconies looking down on to the cafe area, a fountain and on to the lift shaft, which has 4 glass lifts (elevators) lookong in to the atrium. As with everything in Saudi Arabia, it is a smoking area - and the smoke makes its way on to the non-smoking floors. There is a coffee/snack/light food menu available all day - service is a bit slow, but the quality is good. Regardless of what you purchase, it always seems to costs SR110.
Check-in 8/10
Lobby/Atrium 6/10 due ot smoke - otherwise 8/10

Pool and health club are very nice and well resourced - there is a large selection of cycle/running/stepping machines - all working with varying programmes and cardio-monitoring, full gym, sauna, steam room, freezing plunge pool and the smallest changing rooms in the world. Such a shame, as everything else is generously proportioned. There's also a squash court with a/c. The ppol was heated to 28 degrees, which was a bit too warm, while the plunge pool was just 12. Staff are helpful and friendly. Women not welcome - this is Saudi afterall, but a female colleague was accommodated by having a cycle machine placed in her bedroom - which I thought was excellent service. ^
Health club: 8/10 (9.5 if the changing rooms had space)
