Well, we decided against Umalas (thanks peps for the advice) and have booked into oasis lagoon!
We all cannot wait. I went to Bali when I was twelve (quite a few years ago :)) and I have always wanted to go back. We got super cheap flights ( $410 return from Adelaide), cheap accomadation, so we are all set.
I am sure I'll be asking a million question between now and December.
