Norwegian Epic Cruise May 20-27 Barcelona Share Private Shore Excursion

My and my husband are taking a cruise on the Epic May 20-27th originating/ending in Barcelona with stops in Naples (may 22 7am – 7 pm ), Civitavecchia (may 23 7am – 7 pm), Livorno (may 24 7am – 7 pm), Cannes (may 25 8am – 7 pm), and Provence (may 26 7am – 7 pm). I am lining up shore excursions in every port (except in the port in Cannes.) I am doing private excursions (likely will book with DriverInRome) and the excursions for 2 (in a Mercedes) are 500 euros OR 550 euros for 4. If anyone is travelling the same time, I would love it if 2 others would join us so we could split it. I am in a manual wheelchair and would be taking up the trunk space so the 2 others could not be wheelchair bound or require the use of much trunk space. If interested, email me at jimjodicarm@gmail.com to coordinate. THanks in advance!
