I recently had a short but exciting business stay over at Le Meridien in Amman. It was a short drive from the airport - I recall it to be about 25 minutes. The corporate travel agent had arranged a room for the two of us and it came up to only about US$120. The breakfast spread was simply amazing and the opulence of the lobby was beyond imagination. My previous trip to Jordan had been on a shoe string - but with a much fatter wallet today I am tasting the other side of what Amman has to offer.
For business travellers, the newly opened Royal Convention Centre would be a very convenient site to host your meetings. We had use of it for a day and the reception was extremely well-catered for.
We were not too happy with the smoke-stenched room which we had been initially allocated, but a quick call to the lobby corrected that and we had profuse apologies right up to the next morning.
If you are in Amman and feel like splurging a little, Le Meridien would be the way to go.
