We would be there in Amsterdam on the 31st of OCT 2013 by afternoon, I would like to book 2-3 day guided tour package to Paris and Switzerland, what is the best site I can go to? and buy tickets? What we are looking is 1day or less in AMS, 1 Day or less in Paris, 1 Day or less in Switzerland. Is this something that you think is feasible? I did try to search google but it had too many results and gotobus.com was one of them that I found useful but there are no tours starting 31st OCT or later, they have one on the 7thNov and we would be leaving by then. We're ok if we did not go to Switzerland but would definitely like to see Eiffel Tower.
