My mom is getting ready to book our cruise tomorrow!

We're in Cat 8C so that our rooms can connect. Would you believe those two rooms are cheaper than 1 Family Deluxe with verandah? There are 5 of us. Me, hubby, DD (7 1/2 at sailing), DS (2 at time of sailing), and my mom. We were originally going to book the 1 room but then I read on Mousesavers.com that sometimes you can get 2 connecting rooms for cheaper on Cat 9. Well Cat 9 is already sold out or rather there are no more connecting rooms left. So 8C is the next level with connecting rooms. Hope they are nice.
So any advice at what I should start looking at or what to expect on a
Disney cruise would greatly help this newb here!
Thanks!!
Betsy
