Wow!!!! Either sounds like a fantastic choice, but no matter what choice you make will you wish you had done the other??? Maybe you could look at prices to go to both from where you're at now versus what it would be to get there from here. It may be that it's still not that expensive to get to VietNam from here? I don't know ~ it's just a thought I had. I can't wait to hear your decision and how you made it. That jellyfish lake looks SO cool I'd be Soooooo tempted!!!
