Which swiss rail pass is suitable

Hello padmini, and welcome. If you don't intend to do any further traveling in France than just the trip Disneyland-Switzerland, you can best buy regular train tickets for that trip. As for a suitable rail pass for Switzerland: that depends on a number of factors. Do you plan on traveling each day for example, and do you want to explore large parts of the country? Is unlimited traveling important for you? Our FAQ may help you out here.

I can say however that a 4 day Swiss Pass might be a very convenient option in your case: it provides free traveling in train, bus and boat throughout the country on all 4 days of your stay. You could purchase a Swiss Saver Pass for all 5 adults (there are no special senior rates), 1 Swiss Youth Pass for the youth, and the free STS Family Card allowing the two children to travel along for free (provided that they're accompanied by their parent(s)). Further details and purchase options can be found at the Swiss Pass page.
