Globus offers a variety of vacation destinations, not just Europe. They are an excellent first class escorted tour operator that we've used for years. Their guides and drivers are top-notch and very informative. The tours normally include most of your meals, and sightseeing. Allowing you to meet people from all over the world speaking the same language as you. Great way to overcome the language barriers you may encounter in other countries.
Monograms allow you the independence of traveling on your own but having a host in each city. With this package you normally get your breakfast daily and 1/2 day sightseeing tour while the rest of the days you are free to explore at your leisure. It's a great option for those who don't want the structure of an organized tour.
