When looking for hotels, use Kayak I have found that is the best website to book hotels. However they are sometimes a little more expensive because they charge commission. So do your research on Kayak because it is a great website, then either book there go straight to the hotels website and book there.
Airbnb is also a great place to book where youll be staying. Often times youll find a cooler place to crash, for much cheaper, and more attentive service especially if youre in asia. Usually the best bang for your buck.
If you’re looking to go even cheaper, or you just want to meet new people from around the world, you can always look for Hostels. Many are super modern, and are a great place to party.
