Southeast Asia in $760s-$890s RT

We've got a thrifty Thursday threefer (say that five times fast) of super rare routes to Southeast Asia, so let's get right into it...

• Phnom Penh is the starting point for any Cambodian adventure. You can head straight for Angkor Wat if you like, but we'd recommend at least stopping by Koh Dach first for a little rural charm and relaxation.
• Vientiane is the capital of Laos and mayyyyybe the most underrated city in SE Asia. You've got to check out the golden temples of Pha That Luang and get a taste of the food at the Night Market, but save some days to tour the rest of Laos too!
• Finally, Surabaya has some pretty amazing spots too, but you'll definitely want to get out and see the colorful villages and natural wonders outside the city. 

Now comes the hard part: deciding where to go first :-)
