Hmmm. I am not that clued up mate!
I have a contact in Jordan who tells me that like israel, there is really only one 'real' resort on the Jordan side of the Dead Sea.
At this resort you have one leading Jordanian derm clinic called the 'Zara Medical Centre'. It is in the grounds of the Movenpick Hotel. There is also an excellent Spa next to it that offers Dead Sea Water Flotation therapy!
Like the DMZ (?) Clinic in Israel, you pays your 100 quid and get a similar treatment regime.
Now the Movenpick is a top styleeeeeee luxury hotel. It looks breathtaking and is set in its own gardens which are irrigated and full of plants and flowers (unusual for the area for obvious reasons!). A top deluxe room there costs about 60 quid...unlike a bog standard room at a 5* on the other side of the lake which costs nearly twice that.
That's about as far as I have got...haven't had time to research anymore. But when I do, I'll let you know

It's not that I am dissing Israel at all...but I am aware that my P is pretty mild (for me) at the moment and I know I'd like to take a few days out from sunning myself to do something 'else'. There is very little to do or see on the other side, whereas in Jordan there is loads!
Plus, no disrespect to any Israeli members, I have a wee problem with the israeli government at the moment (not a religious thing you understand, more a political thing!).
I think I'd rather visit Jordan and put my money in their economy at the moment. I hope no one has taken that the wrong way... :-/
