That works for me! If you want, we could treat it as a thing that they forget about when they go home? From the sounds of it, the event is pretty much 'do your own thing' so there's not a strict set of rules.

I imagine our kids would be weird about it first, but then decide to just get on with it since they can't get home until the community decides to let them, and they know the weird stuff never lasts too long. I don't want them to be totally OOC on arriving, but it's pretty much all I can think of for dropping characters from their setting there and having them not freak out. Heh, this event isn't very Middle-earth friendly, but I don't want to miss out on it! ;)
