France? ... Italy? ... Mexico? ...
The DW and I went to London/England on our Honeymoon - we booked a Trafalgar Tour package through AAA. It included air, hotel, and a bunch of escorted tours (day trips to Stonehenge, Stratford-on-Avon, etc) - with about half the time "free/unescorted" ... I wouldn't be surprised if they had a London-Paris-Venice combo tour (or something similar ... at least London-Paris).
Unless they speak the language, a tour may be the way to go (and it will probably be cheaper than booking each of trip components separately ...)
And don't forget they will need passports, so they'll need a few months "warning" for the trip if they don't have them already ...
