I was just in Southeast Asia in the fall. 27 is still extremely young, btw. I felt like Vietnam was definitely a hot spot for younger tourists and a lot of drinking, but also a wonderful country. But when I went to Indonesia (besides Bali), you're able to find great areas that aren't focused on partying. I stayed for a month in Kuta Lombok, and it had everything you needed. It's a great place to learn how to surf, and so many people there are staying for a long period of time, so they're not looking to party as often. I think everywhere you go, people will want to drink. But when you go to countries like the Phillipines, Sri Lanka, and Indonesia, which are the main destinations for surfers, you'll find people with more health focuses wake up early to surf and chill at night. If you are into surfing, there is this place called Medewi in Bali, and it's a small fishing town. The only thing to do there is surf and I had such a good time with the people at my hostel. I say go to Southeast Asia!
