Blepharoplasty and tours

I am having blepharoplasty and have a tour scheduled 3 days later and some other tours scheduled over the 2 weeks that I will be there. When I asked how soon I would be able to do sightseeing, they said the next day. So my question is for those of you who combined surgery, spas, and sightseeing/shopping, what are some things you packed that were helpful? I already ordered some lubricating drops (they said I will be given a prescription as well), cooling eye mask, I have big sunglasses, an extra travel pillow, and I am bringing a towel from home to avoid seepage. Is there anything else you wish you thought of for the first days after surgery? I was thinking of getting a big floppy hat, but I am not sure how strong the sun is in March.
