Not sure if anyone else would want to do this but I signed up for Groupon for my Honeymoon destination. I just got hula lessons in Honolulu for 50% off.
You could sign up for where ever you are going and get the deals now vs paying the inflated tourist prices.
Note: I checked with the vendor first to ensure I could book the lesson on the day I wanted with the Groupon and they immediately confirmed it for me.
