looking to travel to Warsau, Krakow, Budepest, Vienna & Prague. Maybe extend a few days in Prague. Looking at Gate 1 Tours & Odyssey. Have never done this before. Want to know which would give us the best value and decent & conveniently located hotels. Odyssey includes sightseeing that Gate 1 has as an option. I think Gate 1 might still come out cheaper with the optional trips. Can,t decide. Need advise.Thank you.
