What a beautiful island. It's just different than a normal city in Indonesia. It was a great place to live where you can stay for the retirement. A very open community, most of Balinese they can speak English, moreover they can also speak Mandarin, Japan, Spanish. I wish I could. Well it's hot but when you get burned you will look so handsome :)There are several place you have to go when you have a trip to Bali such as Kuta, Jimbaran, Nusa Dua, Tanah Lot, Ubud, Seminyak, and many more, seems you have to go all arround Bali. It's not so expensive to spend your time to Bali. The living cost there are quite cheap and to shop won't take so much of your money, and the food are amazingly great. You can taste a very fresh meat such as pork where you can't get somewhere else in Indonesia, I think it's only in Bali.
To have a recreation also a good idea. There are various such as bungee-jumping, surfing, banana-boat, paraceling, snorkling, diving, flying-fish, etc. You can take as much as you can.
