I think it is a great tool, as someone who has this on his bucketlist but no experience it is really handy. Few points of feedback:

1. When I select the start date, maybe autofill the end date with 2 weeks or so. 2. I dropped my email, but that is not something I enjoyed doing. 3. I think there should be a clear reason what is expensive and what not. My 2 week itinerary was 25k. I have no idea if this is expensive (probably not), but to me this feels insane.
