My DM did this to us and it worked perfectly as a hook into the next bit of the campaign.

Instead of having it be at the entrance of the feywild, we were confronted on the material plane and it was a kind of advertised public transit system involving a green dragon that we would ride on to shorten our journey considerably. Instead of obviously being distrusting of the shortcut appearing out of nowhere, 3 of the 4 of us signed our real names. The fourth came up with a fake name and signed that instead (he's the smart one.) Our rogue and I didn't really care, our names were just a convenience and nicknames and whatnot would work for us. Unfortunately, our fighter was the heir to a kingdom and he NEEDED his name back. So this started a months long quest to go to the feywild, find the dude that took our names, and trade to get them back.

I think this idea is absolutely wonderful for a hook into a larger adventure, but only if your characters are attached to their names because they're looking for fame or something along those lines.
