What do you want them to do, have a separate meeting place for people mobility issues and THEN separate into group by SHOREX? You chose a bad tour of Cartagena, mine was excellent. Not ONE shopping stop. I thought Colon was great, that place rated a "smiley face." On the other hand I thought Costa Maya was a total waste of money and time. I had to GET OUT of that place and its artificial EPCOT-ambience and go climb a ruin. As for MIA, whatchagonnado? Your alternative is FTL which is near Port Everglades, homeport of Holland-America, Princess and RCCL. Perhaps you should have re-considered your flight arrangements and choice of cruise line. I'm curious if your experience on the same cruise I took in November is anything like mine. Check my videos and compare.
