Hi Chris Nice to hear from you....re the optional excursions ive already asked on another thread for opinions from previous travellers to Vietnam on this matter..if you key in "Vietnam" on the "Search" facility its the thread headed "Vietnam" dated about 10 days ago. The replies i got seemed to say that it might not be worth doing the My Son trip as it takes up nearly all of one of the days in Hoi An thus possibly leaving too little free time to have a proper look at Hoi An. In any case im sure you will be able to book the My Son trip "on the spot" if you decide to go. At present we have booked the cycle tour only.......even if its raining it sounds like it will be fun. Yes definitely up for the coffee at Heathrow but being a technophobe not sure how we exchange the mob nos. :-))
