Thank you everyone! I have read and re-read all your messages and am deeply grateful for your time and suggestions. <3
Specifically and as briefly as I can be ...
Joan - thank you for the links. I'm sorry that you have suffered with PF too - my heart goes out to you. As for Amalfi - we will be driving our rental car to Sorrento where our hotel has free parking and free shuttles to town. We will either use the bus or a private driver to go further to Positano and the ferry over to Capri from Sorrento's port.
Rae - great advice! I like the thought of just sitting and resting in local churches which also are steeped in history. Despite your mobility issues (which I'm sorry to hear about), I'm glad it has not stopped you from getting around. Venice, Portugal - that's wonderful! And yes, I shall look into Alegria sandals.
Becky - foldable tripod stools - neat idea - thanks!
Lo - Wow, the Vatican 3 times! The Dark Hour Tour is something I've looked at - thank you for your feedback on it. Yes, I have spent many a late night watching videos on driving not only the Amalfi Coast but Italy in general. I like the thought of Scooterama - I will see if it will fit in the budget.
Laura - I guess the word "expensive" is relative to each person's budget :). Unfortunately our weak Canadian dollar doesn't help.
Joe - as a part-time event planner, I am all about details, so appropriate clothing is covered. No sense boring you with how I convinced my bestie to take clothes that will be suitable for Italy, but I did :). Thank you.
Pam - I haven't heard of the Melt Method but will definitely look into it. Thank you!
Gerri - thanks for all the links and resources, and the warnings too :). Thank you for your help and your sweet well wishes.
Nelly - oh dear, you've had many bouts of PF! This is my first, and I just ache to think of people having to suffer this multiple times. Nevertheless, things can always be worse and we count our blessings. Yes, I too have been stretching numerous times a day for the last 2 months and today I had an appointment with an amazing Physio Therapist who has magic hands. I have been using a golf ball thus far, but will look at alternately using a hard rubber ball. Thank you!
Nancy - yes, custom orthos is ringing through my ears :). I'm glad you have had the opportunity to visit Italy many times. Thank you!
Rae - I have weighed many times whether to tell my bestie or not, but being a detail-oriented person, and as someone who knows her bestie inside and out (down to what kind of undies she will bring lol), I believe I have everything covered. I definitely appreciate you bringing it up though, as I have now triple checked my list (money, emergency contacts, meds, attire, etc). The TALE of our trip to Seattle/Vancouver involves business on only 2 days (where she'll be packing light dresses that she can wear for evening dinners in Italy) and the rest a mini vacation for us, so she will be carrying comfy clothes and shoes. I know the bank cards she carries and that they can be used in Italy, should an emergency arise or if she wants to pick up small gifts for her family. A couple key family members who can be trusted with tightly sealed lips know. This trip has consumed many of my weeks in planning, to ensure that she will be comfortable and prepared when she hears the words, "Actually, we're not going to Seattle/Vancouver....We're Going To Italy!" Thanks dear Rae.
Dick - thanks for the warning with Ibuprofen. I'm careful with painkillers as I understand they're just a bandaid, and I'd rather heal the issue than cover it up, but will be taking a few on this trip. I don't drink alcohol (yes, I know I'm going to Italy LOL), so no worries :).
Sandy - thank you for reminding me to be strategic in my walking and to use whatever resources may be available to me. I appreciate your well wishes.
Blessings, Hugs And All Things Good To Each Of You!
