Yes, I wouldn't recommend using the free version of Evernote other than as a trial. As a semi-retired person, I have a part-time solo consulting practice, so it's worth it for me to pay for Evernote and invest the time in figuring out how to use it effectively.
I have heard very good things about Trello, too.
And if anyone has an Office 365 subscription, One Note might be a useful option.
I think the general message is that a note capturing program can allow someone to capture all kinds of information about a trip in one place -- brainstorming, planning, execution (routes, reservations, etc), and memories all in one place, which is really, really good.
