As a Gold, it's better to try to get ER, as it gives you access to EL. As a diamond, I would actually insist on a Corner room, as EL is a benefit anyway. Corner rooms are larger than Executive Rooms, same TV, same table+armchair...
dcshungu, sorry to hear that with the taxis. I remember that the ones in front of hotel were very expensive, but I always went 100m to the RIGHT and got legit ones. Never go to the LEFT for a taxi, as you end up in the Nyugati train station, and that's where the scammers live and breathe
