Petra/Wadi Rum Excursion? (Amman)

Is anyone interested in doing a 2-day excursion to Petra and Wadi Rum next weekend (7/ Protected content ? I am on a budget, so will like to stay somewhere inexpensive near Petra for one night (or stay at a Bedouin camp, but not sure how much that costs?) The Jett bus leaves early morning from Amman and is heads back in the evenings-- 9JD each way. Would be more fun to go as a group, so let me know if you are interested in joining!
