What is the name of Rick's guide in Prague?
Andree, I assume you're referring to the local Guides in Prague? Rick likely uses more than one local Guide there. As the previous reply suggested, the Guidebook would be a good source of information on this subject. Cheers!
Rick used these people; so did we and they were great. We had Gabriela, who was terrific. http://praguewalker.com/
If you are interested in a walking tour there are many. We used the girl with the Lime Green umbrella nad were very pleased.
I have used "Personal Prague Guides" several times, on different trips, and they are always excellent. http://www.prague-guide.info/
