Well done luckygirl you have made it! I hope you are rewarding yourself with a big
and maybe a croissant and the peace and quiet of a house once the guests have gone.
What you say about your DH not enjoying going out totally resonates with me (and my DH, while he has many chronic issues, does not even have the added complication of PD)
Trying to find an excuse for not going is par for the course and I sometimes have to turn a very deaf ear , also wanting to come home even when an early departure is quite impractical. It takes much of the joy out of planning any event or visit. Even a visit to the cinema to see a streamed performance of Twelfth Night yesterday (30 minutes away, easy access, comfy seating) was a bridge too far. I knew as soon as he woke up it was doubtful, the pained expression, the backache, the trips to the loo because of his diuretic, the grumpy reminder that I had failed to book him a podiatry appointment......
Saw it coming but tried to ignore it!! In the end I just went on my own, but got a chilly reception when I got back because he "had had to have a lie down" in the afternoon.
Some battles are worth fighting, with others I just keep my counsel, have a
and try not to seethe inwardly. 
I know I am not alone in this, just KBO as my dad used to say!
