Yes its only the new 20s that it would not take, old ones and tenners were fine - never had a 50 so don't know

Reception would either change a new 20 to egyptian or swap your new ones to old for you. I know there is a bank there but I never saw it open as I tended to change money in the evenings.
Mel - I wouldn't worry , as you say they can't change the location and that is stunning ! Though as Jay says the Blu Club may well be gone and I think that will make it feel bigger as it seemed to have an Italian side and a rest of the World side !
