Hi Bob,
I've looked into this one for you and the Dubai stopover itinerary is with our content exec to upload onto the website so there will be details of this online at some point.
I have looked in the reservations system and there are currently five 2015 departures with the Dubai add-on.
In terms of doing this more for our long haul tours, Will is the man to speak to and you know that he keeps a very close eye on the community for your comments and feedback.
Kindest regards,
Julia
