Travel without a purpose to Bali

If you go to Kuta, which is the party capital of Bali, you can easily stay up all Saturday night (or any night) clubbing. There are many bars and clubs around.

Considering you only come for two days, you don't have to bring a lot of luggage and can leave it at the clerk room of a club.

The climate on Bali is very similar to Singapore, so you can also easily spend the night outside, walking around town or hang out on the beach.

When I was on Bali I arrived by bus in Denpasar (the biggest town) at 2am. I was okay with walking around the city with my bag at this time and I ended up watching a world cup game from 3-5 am before looking for a hotel in the morning.

Besides those two places I expect most of Bali to be pretty quiet at night, so if you don't have a hotel room, there is not much to do.

In Bali actually you can get room that is actually very cheap. But I try to understand your aim to travel without staying in hotel. There is one other option for such purpose, you can rent cheap car. You can moving around with that car and sleep in the car at the night at anyplace that you want. The cheapest that I know is Suzuki Katana that can be rent only about 100.000 per day. Gassoline itself is very affordable in Indonesia. So you can hire the car to be delivered to airport on Saturday and return the car again in airport on Sunday.
