Kidgoingon40 - Welcome!
What a wonderful connection you have to the GF, I'm glad you are able to switch for your anniversary. At which US resort are you booked? We just returned from a HRH/PBH stay.
Which category room do you have reserved at the Grand? I hope you won't find the construction too disruptive, but it's possible you may. The beach pool area is completely closed in with fencing, not very pretty at the moment. I posted some photos a couple pages back of the beach, it is fenced off and is just a narrow strip now, no hammocks. The pool activities and movie on the beach have been relocated to the courtyard pool, so it is more hectic in the afternoon/early evening.
If you are booked garden view, you may wish to request Sago Cay - or at least a room facing the marina. If you have a TPV booked, you will automatically be facing away from the courtyard, so that's OK.
Whatever category, I think I would try to stay away from Big Pine Key, as the lagoon view rooms will face the construction and the garden view will face the courtyard.
HTH!
