Just some feedback.
Hotel is decidely mixed but good for those arriving late/leaving early and/or going to/coming from Petra and the south.
Most floors appear to be smoking. Free and ample parking. Basic but cleanish rooms.
Hotelclub does seem to be the place to buy the stay. Walkup cost is JOD70 (double occupancy) + 25% tax/s.c.
Buffet breakfast varies from day to day. The mezze (6 plates for JOD 5) in the FC restaurant is a bargain if you need to get food here.
