Priceline is a really bad idea. I tried booking a hotel has a priceline quote that is cheaper than others. This time I played safe and book as 2 rooms, 4 adults total. Priceline confirmed my booking. But 10 minutes later, I got 2 emails from agoda saying my reservation is cancelled due to payment issue (my card is perfectly fine, as I used it without issue afterward). But Priceline still showing my reservation is fine and dandy. It would once again be a disaster had I ignore the agoda email and show up for my hotel.

In summary. Don't book your oversea hotel using priceline, especially if you are traveling with kids. You could be in for a rude surprise.
