Royal Princess Upcoming Drydock

We understand that the Royal will head to drydock probably in an Italian shipyard on September 25th.  The drydock will last about 12 days, until October 6th, 2016.  After carefully examining the deck plans it would appear no drastic changes will occur such as opening of the central stairwell above deck 7 or the addition of the aft plunge pool found on the Regal.  The main changes we can find are that some of the mini-suites will be upgraded as part of the "Club Class" minisuite program.  Additional info about that program can be found here: http://www.princess.com/learn/ships/staterooms/club-class/.
