Bali.
Why choose Bali?
...The infinity pools!!! (Other people would choose it for surfing, yoga, adventures...)
Where did I stay?
...Kuta. 3 days in a hotel, and 7 days in a hostel (H-Ostel).
How did I get around in Bali?
...I chose the "Airport Transfer Service" from Kura-Kura Bus. They also offered a free 7-days bus pass if we booked their airport transfer service. I didn't want to get scammed by the taxi drivers at the airport, so I decided to book the service beforehand. Their bus route covers 5 line, and I was able to go to Nusa Dua, Jimbaran, Seminyak, and Ubud. When I'm not on the bus, I either walked or shared a ride with my new friends. It's hard/"dangerous" to use Uber/Lyft/other ridesharing apps there. It'd be easier if you have a sim card so the driver can contact you discretely. Most local use Grab/Go-Jek though. You just have to be super careful about not letting taxi drivers / anti-ridesharing people see you or the car.
Where did I go?
...I basically hopped on the bus to go to each location/per day, until I've completed all bus routes. Kuta - for releasing baby turtles and souvenir shopping (since that's where I stayed). Seminyak - for Potato Head Beach Club and nightlife activities. Ubud - for Monkey Forest and "cultured" feeling. Nusa Dua - Water Blow, the beach, and The Pirates Bay. Jimbaran - for more fancy hotels/rooftop infinity pools. I also went to Uluwatu Temple from here (we got a taxi).
