We want to visit Paris & Florence with a tour company. I am having troubling comparing Globus, Go Ahead Tours, Grand European Tours, Collette, Trafalgar, etc. How do experienced tour takers compare these companis? Thanks.

Price of tours and sites visited. What are the available discounts off of the brochure rates? Insight is a little bit above Globus and Trafalgar.

I have only used Globus so I really can't compare with the other companies however I have always been happy with the Globus tours.
Be sure when you compare companies to take into consideration the included optionals. On many budget companies that appear cheaper you have to pay extra for things that are included with the more expensive tour compnies.
From what I have seen on the boards Globus and Insight have the most happy,non complaining clients. If you do a search on these boards there are several threads that compare the various tour companies.

Also on Premium and First Class tours, the hotels are usually more centrally located than on the super savor or budget tours.

After 5 wonderful Trafalgar tours, I chose Insight for my retirement gift to myself. More $$$ but the smaller-sized group and better hotel locations more than made up for it. I am now going on a Globus tour in June.
I pick my trips based on the itineraries and what is included.
Whatever company you chose, you will have a wonderful time.
