Mechellec, yowza, what a schedule! I'm so sorry to hear about your father-in-law, especially since it's immediately on the heels of your daughter's wedding.
The hot springs sound fab to me! I think I'd brave the stairs for that treat, but yeah, bring the cane, "just in case." You'll never be sorry to have brought it, but you could really regret not having it.
I applaud your gymnastic moves but I know you're right about the kids, lol!
All that cleaning and prepping and walking sure sounds like natural PT to me! Actually, it sounds much better; brava!
