Ok, got word from S-I-L that she's not going to have time to play in the pool, and others from her family aren't going to be making the trip for the family gathering. So I now can go ahead and drain the pool.

I'm going to let the FC level drop below 35, before actually draining.

I'll take the water down to 3"-4", heavily dose the remainder with bleach, then scrub the heck out of it. Also will be trimming the algae hiding excess flaps of liner seams from the inside of the pool. I do have a question, since I am taking the pool down, should/could I use a copper based algaecide in the clean-up?
