Yes the GCH is being worked on to have the shops all moved to the first floor up front. Captain Cooks is getting larger, The arcade is moving to the GCH. The rooms are going to get redone completely starting with Tahiti at the end of April, The Tonga suites are in the middle of being updated.
They are also doing a new lobby concierge desk that will be where non-concierge guests will go to get their tickets or make PS arrangements, etc. so they do not have to back up the line over at check-in. The concierge will now be called the King Kamehameha Club level. There are a few more things but I have been asked to wait to say anything till they have the plans confirmed. My pages will be back up on Monday for more details on the changes and I hope to add more info soon.
