We have just returned from a standard tour but having heard about trouble getting in with scope and large SLR we took just our compact binoculars and a small zoom camera for incidental birding.
We had no trouble getting into Aqaba but had three lots of security checks with camera and small bins being examined and swabbed three times and us held up for about an hour when getting out.
Not sure if it is due to heightened security - American peace plan being announced and possible unrest forecast had anything to do with the change from getting in v out.
Really glad we did what we did although my photos Rosefinch and Wheatear are pretty rubbish on the little Lumix.
One guy with only 300mm lens and SLR took even more time to get through security on the way out but again didn't get stopped on arrival.
