I am guessing you are coming from India, or somewhere else in Asia, and using one of the notoriously horrible travel agents there who suggest impossible itineraries based on bus tours to places they have never set foot in. I am good friends with an Indian travel agent and have talked at length with him about how these insane trips evolve.

Please start over. Drop Switzerland, drop Disneyworld, drop the Lido, but first and foremost, drop the "travel agent!."
