kazman,
Not sure about exec floor (or lounge) - don't think there is one. I've stayed fairly recently as a Gold VIP & was also treated very well. Was put in one of the renovated rooms - very nice, with a lot of light colours, and a modern feel. Definitely one of the best Hilton / Conrad rooms I've been in, if a little on the "not big" side !
Let me know if I can help in any other way.
BTW, the Hilton, Dublin (just around the corner from the Conrad @ 500 yards) has recently installed executive rooms. I will be staying in one on 6th Oct & will let u know how I get on if you like. Rates are about 50-60% of the Conrad @ ~$120US for a double room - I get upgraded to an exec room as a Gold VIP (quote from reservations agent !!). Exec rooms here cost about $200US.
