Thanks.

Given that the 20% discounts are offered at quite a range of the most
popular attractions (plus a few restaurant chains) there is probably
the opportunity for the serious tourist to recoup the entire cost of
the Visitors Travel Card - hence my feeling that it is a better deal
for overseas visitors than a standard travelcard.

Probably in one visit to Vinopolis ;-)
