Last time I was in Ubud in May, walking around the Royal Palace and was inundated by crowds of rowdy mainland Chinese tourists... Not the "Eat Pray Love" Ubud we knew of anymore

There are one or two wreck dives around East Bali I think and a good chance to see Mola Mola if you are there in season. The reefs are similar to around Nusa Penida but slightly more untouched.

Don't worry if you want to move between Kila and Nusa, Aman is extremely flexible, as long as availability allows, they will be very happy to accomodate.
