FWIW, Disney has been pretty quiet on what all they have going on in terms of GF refurbs, which IMHO makes it annoying to try to plan a trip there for the near to mid term. The Big Pine Key DVC conversion lasted from roughly March through late June 2022, so let’s round up and say 4 months. They moved almost immediately on to Boca Chica which is nearly identical size to Big Pine Key, so let's say July-Oct 2022, next building Nov 2022-Feb 2023, next building Mar 2023-June 2023, etc, etc. Not all of the upcoming buildings are the same size and they could always do multiple buildings at a time, so it’s hard (if not a fool's errand) to estimate the possible timeline exactly.
To use Disney’s vague phrase… ‘multi-year’… as taken from their most recent DPB post about V&A’s reopening.
The reopening of this fine dining staple comes as part of the multi-year transformation of Disney’s Grand Floridian Resort & Spa, honoring its rich history at Walt Disney World Resort while enhancing its iconic Victorian charm and elegance. This grand transformation began with the addition of Enchanted Rose lounge and the reimagining of Cítricos – which features sophisticated, subtle nods to beloved Disney films – and continued with the reopening of The Grand Floridian Spa. Victoria & Albert’s and the newly enhanced and expanded accommodations at The Villas at Disney’s Grand Floridian Resort & Spa will open this summer. The transformation will continue with updated offerings across the resort over the coming years.
So unfortunately a lot of unknowns and IMHO something to keep a close eye on. We've had great 'during renovation' stays at places, but we go often and are fine to go with the flow. Depending on the progression of work and one's tolerance for seeing things like construction walls, workers around, wanting a 'perfect' GF experience, etc, it may be tough to set your sights on GF at least through 2023.
