Cool. Let me give you some insider knowledge...
When you get there, you wont see a 'hotel' as you are probably imagining it. It actually doesnt look at all like a hotel from the outside. Its just a door with logo on that leads into a small corridor. You will find two burly bouncers stood in the corridor. They are totally cool and you talk to them and they book you in via a machine a bit like an ATM
You do this by using the card that you used to book the room and your receipt and room key pop out of the machine... This takes about 30 seconds. Then they let you past and you'll see the bar area at the back, and thats where you get to the lifts. The hotel part is all the floors above, but it just has a very small footprint (The Corridor) on the ground floor...
AS I say, the place itself (Once you are past security) is very nice, with little touches like a stack of empty water bottles and filtered cold water dispenser on every floor, so you can take a fresh bottle of drinking water out with you. A complimentary touch
What I'm trying to really say though, is when I arrived first time, I thought that I'd been had, it wasn't a real hotel and the two big guys were going to mug me ! However within a few moments I realised that it also means you are nice and secure. No one can get past the guys without a room key so its nice and safe
Enjoy
