Lots of great info here! Thanks!

I have been lurking for a while, trying to learn all I can but here's a question:

I have a companion cert that expires soon, so a new cert should also be arriving shortly.

Hubby and I want to bring our two teens with us to Hawaii this winter. Can I book two of us (one full fare and one companion cert) now and then when the other cert shows up, book the other two?
