... but can be EXPENSIVE!
The cost, especially during major exhibitions, is one thing, and a known factor, but my main objections were:
1. Facilities close at 2am, including the rooftop area, whereas most of us with jetlag need somewhere to go.
2. My room had a connecting door to the next room. It might as well have not been there, as every cough, grunt, TV station and midnight call home from next door was loud and clear.
A real disappointment.
