How do I book hotels cheaper using a VPN?

Set your VPN to a Thailand server before searching on Agoda or Booking.com. Thai IP addresses are shown prices 20-40% lower than US or European IPs — for hotels anywhere in the world.

Is using a VPN to find cheaper hotel prices legal?

Yes, using a VPN is completely legal in most countries. You are simply browsing the internet from a different location. CheapStay teaches you how to find the best publicly available price.

Which is cheaper — Agoda or Booking.com?

It depends on the destination and dates. CheapStay compares both in real time so you always see the lowest price. In Asia, Agoda is often cheaper. In Europe, Booking.com tends to win.

What credit card is best for hotel bookings?

Chase Sapphire Preferred earns 2x points on hotels with no foreign fees — best for most travelers. Amex Gold has the biggest welcome bonus. Capital One Venture is the simplest — 2x miles on everything.

Can I get cashback on hotel bookings?

Yes. TopCashback and Rakuten offer 3–8% cashback on Agoda and Booking.com. Stack this with Thai IP pricing and a travel credit card for maximum savings.
