I went on Thursday and the only benefit I get from it is getting some extra details of any countries I plan to visit soon from the local tourist boards. I got a couple of excellent street maps of TLV this time.
Oh, and deals on travel guide books that Stanfords/Dorling Kindersley/Rough Guide tend to offer at their stands.
Not surprised I was sent three pairs of complimentary tickets for this year, obviously can't get rid of them all...
