About that elevator to Acropolis, getting the use of it is iffy. Just the fact of having trouble with stairs, or a gimpy leg is not enough; one needs advance reservation & specific time appt. to use it, and from what I've been able to ascertain from friends of mine (Destination Experts in athens for Trip Adv) you can't get it just by the limited mobility of ordinary aging... usually wheelchair or crutches, or a MD's note attesting to serious disability would be needed. If u get use of the lift an escort is permitted. However, it would be vital to RE-check the day before, to assure that an attendant to run the lift will be on hand. Alas, cases are known when reservation & appts are solid, yet somehow... no attendant is there. Folks, it's Greece. Check, recheck, and doublecheck.
