Hi Bob,
I did the Jordan trip in April of this year so you may like to read my review if you haven't already done so.
Regarding the Wadi Rum visit, because you're going through by coach (which basically sticks to the main road), you only see a very small part of the area and consequently don't see or get to appreciate the greatness of Wadi Rum.
Having said that, what you do see is spectacular and the lunch at the Bedouin tent is very pleasant but it only makes you wonder at what you would have seen with the advantage of a 4x4 vehicle.
I really hope that JY can find a supplier that meets their H&S requirements soon, so that future travellers can enjoy the best of Wadi Rum and it's unique atmosphere.
If you have any questions regarding the holiday I'll be happy to answer them.
Cheers
Mike
