Mary, I understand your ordeal with The Boot! A year ago I was in the same boat, with a Disney trip looming and that same heavy HOT boot on my foot. By seriously a MIRACLE I was completely healed days before the trip and went BOOT FREE. I was in awe. I was in crazy pain just a week before yet had zero issues at WDW! I know your situation is different than mine was, but I just wanted to post that I can sympathize with The Boot and how hot it is in the middle of summer...and how it gets old walking around in it with that uneven gait...I remember my hips hurting at the end of a day.
I think the
ECV will work out just fine for you, don't worry about slowing the troops down - it will just make everyone slow down too and enjoy the trip even more.

Besides, I think both ladies, and you, are most excited about spending time with each other than running from ride to ride.
And yes, cortisone shots HURRRRRRRRRRRRRRRRRRRRRRRRRT! Owie!!!!!!!!!!
That would RULE!
