Was a bit harsh with the first review because of the freshness of the situation. In all fairness the unpleasantness of the tour guide couldn't be attributed to Bob who is the trip organiser at the place. Bob is extremely helpful and very nice. The safaris and tours organised could be a bit better, it all depends on the package you choose.
Point of advice, organise transportation to the places you want to go to. Cycles, cabs are the best for nearby places. All in all probably the best place to organise stuff but it's a good idea to ask around about pricing in general before.
If you are looking to do any activity in sinai .. this place is where you need to go.
They will get you whatever you need, arrange it for you and pick you up.
Very badly organized trip to St. Catherine, problems with payment and timing!
