Not everybody can handle multiple days of bicycling.
A lot more people can handle multiple days of driving.
A van can also move multiple people, or a lot more stuff.
Seems perfect to me, if you live within around 60 miles of a nice weekend vacay spot... maybe I'm spoiled by growing up in the PNW, but basically just most of it is within 60 miles of a decent spot for a weekend vacay.
Even if its further away... just do things like an old fashioned road trip, plan out your travel times and routes and days, such that it all lines up. If that means a day or two in a slightly less interesting spot while you're recharging... who cares? Bring beer, a deck of cards, a horseshoe ring or bocci ball kit or something.
