I'd say a medical file is a good idea...and put a list in it of everything you want to mention/ask. I do a file now with a list of all my symptoms and when they started, a list of my meds, a list of the tests I've had done and put in a new list of questions each time I go.
Can you find a hotel online and book it beforehand? That way you can check out room facilities, food options, etc, etc way ahead of time.
