The renovated rooms on the 3rd floor also still have the manual AC Control. I was in AKL Concierge on this same trip and experienced the automatic thermostat for the first time, it's a little different.
What is different in the renovated YC rooms are the elimination of the 2nd phone in the bathroom as well as the TV speaker over the sink area. In it's place they built an additional tile shelf above the faucet area in the same material as the sink counters which runs the entire length of the counter. Additionally, they've added an additional 9 inch deep shelf area just below the sink counters for you to store toiletries or any other necessary bathroom items you may have brought with you and it also runs the entire length of the counter.
I didn't need to use this new feature as there were only two of us in the room, however, I can see where this space would be extremely useful or handy if there were 4-5 people occupying the room. The new "tall" dresser only has 4 drawers instead of the old one with 5 but the drawers were still deep and very practical.
As a point of comparison, this was the first time I stayed at the AKL and I discovered that their bathroom sink area already had the additional shelving feature above and below the sinks. they also still had the second phone extension in the bathroom...never used it though, but it was there.
In addition, the in-room safe located in the closet at AKL was twice as large as those found in the YC/BC.
I believe someone reported these changes in an earlier thread maybe about a month ago, so I apologize in advance if this information is rendundant to anyone. It's just that it's easier to write about the changes now that I have experienced the changes first hand.
And shame on the guest who told me that the 5th floor was pretty much done already, I guess I assumed a bit too much.
Oh well, have a great time!
