Oh I can't decide between the two!
LA was fantastic! But it was a competition and lots of things were arranged for us - yes that was a good thing, we got the free tour of Hollywood and the days with the cast - but we only had one day free, in which I went to Universal Studios. Being a person going into the Media Industry I would have loved much more time to explore LA - but we only had 5 days!
Australia was brilliant too, but in a different way. That was more of a proper holiday, we had days out, we spent time with the crew and cast, but we also spent days just relaxing around the area. Sitting on the beach, walking up to the lighthouse, taking a seaplane trip etc. It made me realise that I actually want to live there one day - a much better quality of life in my opinion!
I don't know, I might say Oz was the better one - LA was a bit rushed!
