WEEBOBBY - the Amans are the hotel group of choice for a lot of celebrities - when we were staying at a hotel next to Amanpuri Noel Gallagher and Meg Matthews were staying at the Aman as have the likes of Kate Moss and Prince Andrew!

Musken - when you're staying at Amanusa - you should go to see the Kecak dance at Uluwatu at sunset. Your driver will wait for you and find you at the end of the performance. I'm assuming you're taking your son - he will love it. It's a lot more boy friendly than say Legong.

Keep your sunglasses etc. well concealed when walking up to the temple as the monkeys are adept at snatching unsecured items.
