Regarding the 2BR recommendation, I wonder if it would work out where if you got a 2BR lockoff for the portion of the stay where your family will be there, they would be able to keep you in the same studio for at least part if not all of your stay.
Leg 1 – just you in the studio side
Leg 2 – your family moves into the 1BR side for the 4 days and you all have use of the whole 2BR including kitchen and laundry
Leg 3 – your family checks out and the kickoff door is closed again
It may require 1 move for you but I highly doubt it would require 2 (and potentially none).
I’m not sure how the points cost works out this way, but you’d save from having the 1BR the whole time and being cramped in there for 2 days, and you’d be able to do laundry mid-trip. This is probably how I would try to make it work if it were my trip, and I’d just flag it to the front desk in the room request and when checking in.
FWIW, we stayed in a 2BR garden view in the Ewa tower and could see the ocean. The 2BR was so nice and spacious (3 adults, 2 kids under 5).
