I am definitely feeling that boredom and I really don't want to. We are taking our 5th
Disney cruise of this year in December (it is the Merrytime Christmas though...haven't done that since 2014)
At this point, we love to take them for the relaxation part because we know that we are not going to go to the shows, won't get off the ship and can leave the phones and electronics at home and have a good time as a family.
After looking at the itineraries today for 2018, I am thinking we are going to have to go to Alaska, do a Transatlantic, leave out of San Juan and do a PC cruise just to stretch our wings and to stay with Disney.

Since we already have one booked for September of 2017, I think Alaska in May is going to be our next sailing.
