Nice! Using it now for a trip I'm leaving on in a few hours. :D
It would be nice to share a link that folks can suggest, without signing up. Kinda hard to get a bunch of people to make accounts on something last minute, and I'd be okay being the one who slots suggestions into times and does general management.
EDIT: Adding events is a bit painful. I've been conditioned to click on a calendar where I want the event, then fill in details. Running through every field of a date time in order (day, hour, am/pm, etc) for start and end is a lot of friction.
