I'm having trouble figuring out what the "Create one now, free"-button does. What am I creating? Also, "plan the same trip" doesn't make it immediately obvious that you're planning a trip together with other people and not just planning to have the same kind of trip some of your friends might have taken earlier, for example.

After browsing for a little while everything seems clear enough, but I would suggest having a professional copywriter go through the landing page.
