Very good, well organized.
They checked in on us to confirm the trip was going well.
The only issues I had were: The first hotel had noisy air-con (but actually really good food), Wally also organised a boat trip at Aqaba that was good, however, I think it would have been great if we'd also known about the Neptune / submarine boat there as one of the group was not a confident swimmer, and we would have happily done both trips (and had the time). Otherwise, I found it a very stress-free and well-arranged trip.
Wally was a very interesting fellow to have take us through the region. He definitely was passionate about Jordan and really wanted us to enjoy ourselves.
I'd suggest spending late evening / early morning in the Dead Sea - this area would be too warm otherwise! Also, be aware that the Jordan Museum is not open very long during the day, so if you want to see the Dead Sea scrolls, keep that in mind.
Snorkelling in Aqaba and seeing Petra.
