On none of those trips did we delay or inconvenience the others. We were always among the first on the bus, taking our assigned seats and stowing the walker out of the way. We actually required less attention from the PDs than many of the more able bodied, who wandered off for shopping, photo ops, or whatever. We made it a point to have the PD warn us of situations where we might inconvenience the group, so that we could skip the activity, leave early for the next location or whatever. We appreciated the chance to take these wonderful trips and would not detract from others enjoyment. We have encountered others that more or less demanded assistance from fellow travelers and would not be one of those. We were also upfront ith the travel counselor to make sure that the paricular trip was suitable for us. Actually, having the walker lessened any impact we may have had on the group, as it allowed us to maintain the pace of the rest of the group, being able to sit at stops during the tours
If you have any mobility issues, do not fail to avail yourself of mobility assistabnce available in the airports. All airports have mobiloity aids there to help you with wheelchairs, golf carts or whatever. You will also get priority with security and imigration, such that, on arrival or on an intermediate flight, you will be among the first at your meeting place.
If we found that we were inconveniencing any of the other travelers we would not be traveling.
By the way, the Tall Ship trip that we took had many ports of call on the Dalmatian coast. There were many challenges, due to the architecture of the cities, but it was doable, as long as you could negotiate some stairs without the walker.and recognized that there may be some things that you might have to skip..
