We have used e-tickets for our last two cruises with Royal Caribbean and will do the same for the upcoming October 28 trip.
I'm just as excited to get the notice in my e-mail that the docs are ready as I would if they showed up in the mail.
We just booked our cruise on Tuesday for any inside stateroom and today I was able to get the actual room number by checking my reservation on the RCI website.
As far as the luggage tag - I print off the tag and then insert it in a plastic luggage tag where the personal ID usually goes.
