Please send me your recommendation for a guide. I had thought about taking the bus into town and doing Athens on our own, but was concerned about my Mom and my sister's Mother-in-Law being uncomfortable. I have heard that at times it is hard to find a seat and people aren't good about giving up their seat to seniors. I don't mind standing, but would hate for the two of them to have to. I have never been to Europe, so I am just going by what I have read and heard. Any insight would be appreciated.
