We're planning a trip to Switzerland in July.
We're still piecing together an itinerary; at the moment we're tentatively planning to visit Lucerne, Lauterbrunnen and Zermatt, where after a day or two, we would hop on the Glacier Express to St. Moritz. Obviously, Switzerland is a pricey country, but even so, the price of the trip seems extravagant.
Any opinions on whether the trip is worth it, considering what else we would/could see in the normal course of travel?
If we do opt for the Glacier Express trip, any other advice would be appreciated.
