1. Swiss Half Fare Card (1-Month for Visitors)
There is a strong possibility that I will end up renting a car for most of my trip throughout the country, thus make the Swiss Pass and Swiss Flexi Pass relatively expensive. If I spend the night at Grindelwald (via car), then what's the most cost effective ticket to make a day trip to get to Jungfraujoch? It seems that the Swiss Half Fare Monthly Card for Visitors (99F) is a good choice as long as I use it for a couple other rides when I don't have a car? My total for the trip would then be 99F + 81F (return), just 20F more which I can easily make up with a couple other trips?
Does the card offer any discounts on museums? I thought I saw that mentioned on another post but I can't find any wording officially.
2. Also, during my trip, it will be my wife's birthday as well. Does the "Happy Birthday Travelpass" allow her unlimited travel throughout Switzerland. Can she get to Jungfraujoch using this fare (weather permitting of course)?
