I did not go into the grotto,
DisneyGrl. I do not think it was open/operating when I was there. Plus I wanted to catch PhilharMagic.

I think it's safe to say everything is still about the same.
Sew - That's not something a Cast Member is allowed to do. Usually if a costume is going into retirement, it is destroyed. That's not to say I wouldn't make a certain purchase on Ebay. . :lookaroun

The Exxon logo, however, is being removed from the patch.
PurpleDragon - I do not think you'll see much of anything until a new sponsor (let's hope!) takes over the pavilion. I did, however, notice white screens (when looking at the roof from the construction wall); these might have been there already. Once I find out anything, it will be up ASAP. In short: for now, I don't know of anything new going on in there.
Nothing new on SeaCabs,
jmaxwell. I wasn't able to make it in Seas, but last I heard, Disney had installed the Nemo hollograms but found a possible reopening too expensive as potential leaks have been discovered.
