I personally *only* use Expedia for domestic travelling and hotel booking. I've had a few bumps in the road with using their app, even with playing it safe-- never booking Bed 'n Breakfasts, VRBOs, or anything that doesn't have a manager-- but even with the few misunderstandings and horrible circumstances I'd found myself in, the support team came through and managed refunds and credits to keep me going. Best thing to use when on vacation in the USA? Probably not. But they at least try to fix their mistakes wherever they can, even if their terms and conditions say otherwise. That's all I can respect, and I appreciate them for that effort.
