Glad to hear that you had a good experience with the neurologist. It may actually be a blessing to have a new set of eyes looking at things.
I can't believe you are going for 10 days!!!! That is awesome! We did 10 days last May and it was so nice. I didn't feel like I had to rush around and do everything all the time. We just took it easy and enjoyed ourselves.
And I'm just going to say "Chicken!" to changing your mind about the split stay.

We have stayed off-site our first night for the past few trips, so I've always packed an additional overnight bag. Last September, we stayed at 3, count 'em, 3 resorts!

That was a little much.
This September, we are doing a split stay at AKV and BLT. Luckily, we had to buy two new bags for our vacation this month, so I have two new big bags that I can split things up into. I'm hoping it works out okay.
Can't wait to hear all your plans! I wish I was going in May this year again. Maybe next year.
