It's not a deal, but... this is interesting. Hyatt Hotels and Resorts started the Gift Registry. This means that, for whatever reasons, you can put that scuba diving or water sports on the gift registry online to create extra memories!

So... why not register your next scuba experience under your own gift registry?
