Depends on how much you want to see Sir Elton. It is not every day that you'll get a chance to see him belt out a few tunes on the old Joanna after all.

I reckon you'd be looking at an easy $100 a piece for the tickets, so if the hotel isn't a massive leap up in price from your current accomodation (or a step down for that matter) then go for it.

Life's too short not to enjoy yourself when you get a chance ^
