Photo update as of Thursday, Feb 26. While the construction walls came down earlier this week, today was only the second day Plaza Gardens West were open to guests. WDWMagic has posted a great video and pictures. Here are a few photos of guests enjoying the area later in the day. Some guests were even picnicking on the grass. Even though it rained just a day ago, the grass was dry. Perhaps there is a drain system under the artificial grass.
The castle crane: the "ice lights" have long been removed, so I believe Disney took the opportunity of having the crane in place to do some upkeep on the castle. Workmen in a cage were hoisted up to work on the turrets.
Workmen were busy on Plaza Gardens East all day, installing artificial grass and landscaping. A cast member said Plaza Gardens East would open tomorrow. That may be if they work all night, but I think a couple more days. Following two photos are of Plaza Gardens East taken over the construction wall.
Below photo is of the expanded "dining area" for the Plaza Ice Cream Parlor across from The Plaza Restaurant, to mirror the expanded area across from Casey's Corner.
On the public side of the construction wall, the tables and chairs across from The Plaza Restaurant have been removed recently, in preparation for removing the construction wall.
The restrooms at the base of Tomorrowland Terrace Restaurant are indeed open. Here is a photo of the large planter being constructed in front of the restroom entrances. The white color and concrete shape/form match the existing shapes around Tomorrowland Terrace Restaurant.
Around the hub itself, preparations are in place for new pavement and the planters are taking shape, similar to the new Plaza Gardens. Note the color detail at the base of the Partners statue.
