Hi Bob
Many thanks for your response and for your encouragements. Yes, the itinerary really appeals to me and Central America has been one of the places on my 'would love to visit' list. I am also interested in Alaska, Uzbekistan and Iran.
After your encouragements, I noted that the item listed on the last day of the tour is - tour not advisable for people with mobility difficulties. This is a little subjective, so I may call JY tomorrow to clarify the issue.
If I do go to Central America with JY and the trip went well, I will book the listed three above next year. Fingers crossed!
Thank you again for your help and encouragements.
Kim
