Just got back from a week in Bali.
My thoughts, Bali is cool.. a lot bigger than I realised and every area seems different to the next. Kuta is a bit of a dump, basically Magaluf for Australians. We stayed in Seminyak which was still quite built up, but had a better vibe about it. Nice beach, if a little over crowded but had good nightlife.
We did a day in Ubud and the surrounding areas which was ace. Felt like being in an Indiana Jones movie or something like that, amazing history and architecture.
The highlight for me actually wasn't Bali, but the time we spent on the Gili Islands which are a small set of islands about 1.5 hours off the coast of Bali. Amazing vibe, bit of a hippy feel to it. There's no cars or bikes there so the only way to get around is by bicycle or horse and cart, and has some really nice beaches with beach bars etc. The nightlife is excellent though, loads of beach parties going on through the night. Gili Trawangan is the biggest, but we actually preferred Gili Air
