Austrian Alps and Italian Lakes | Switzerland  

Hey! I am planning to buy a package holiday. It is a ten days - nine nights coach tour passing by Holland/Belgium, Germany, Austria, Switzerland, italy and France. The programme includes six nights accommodation on a half-board basis and three nights accommodation on a bed and breakfast basis. It is also included the transportation, guided excursions to Lake Maggiore, Andermatt and Alpine Tour and Feldkirch, Innsbruck and Seefeld, Milan, a ride in Galcier Express, and Paris by night with river cruise. It seems a very nice tour. I have no idea how costly are these places we will be travelling through. The tour itself will cost £560,00 including everything above, but I wonder how much I will need to spend (food/extra fun/souveniers)during the tour. Does anyone have any idea/suggestion how much Euros an average tourist would need for such a tour? Has anyone ever traveled in the Glacier Express?
Thanks!
