Interesting project. So this mean that the user - who is buying the travel/trip/holiday etc plan is going to receive it much cheaper,on the other hand it is more money for the hotel and so on. What are the ideas for the crowdsale? Where it is going to be,payment form etc. I hope it is not going to be on your site - because it will crash and will render it useless and less trustworthy than through and exchange imo.
