Tripcaster: 

Planning a month-long trip this summer, thinking South East Asia, but very open to suggestions & recommendations on where to go in the region.

Where should we go?

I work for Ethereum at the Ethereum Foundation.

Vietnam and Thailand. I would've said Golden Triangle a decade ago, not anymore

If going a bit more west: Northern Pakistan, Southern India

Where specifically would you recommend in Vietnam and Thailand?

Thailand: I like Koh Samui. most of Thailand is amazing, Phuket and Phi Phi are _too touristy and busy_. Chiang Mai can get warm and I don't like the animal imprisonment but good food!

Vietnam: HCMC

contrasts: one is beach with great night life and other is a super busy, populous city with great food

Thailand Island Recs:

Thailand
1. Ko Phi Phi - beautiful island, home of the famous Monkey Beach. Fun nightlife if you're into that!
2. Ko Tao - a diving island, more developed than Ko Phi Phi. Lots of great scuba diving there or free diving if you're into that. 
3. Ko Samui - a more developed and larger island.
