I bought an Entertainer when I was in Dubai just to use for a couple of things (Desert Safari, Wadi, Atlantis and a couple of eating places). Each one of the things I used still has another (or two) vouchers of its kind remaining. We were staying with friends the entire trip so ended up being shown around/fed/hydrated not at our expense.
So... anyone want to buy? I've got the card still and haven't registered it.
As it is basically full, would like to sell for 200 AED equiv (so £35). Based in London. Still saving you 95 AED / £16.
Let me know if interested by PM or reply here.
