if he hates driving why risked the danger of not enjoying one self and fight during a honeymoon.
travelling from A to B takes sometime usually at least 1 hr. if U are not type to hike just take snap pics and leave u may only scratch the surface. The best views often requires some leg work. will he be tired and hit the roads? alot of things to consider. when u hit Utah u get many nice places to visit ie Arches etc. u don't want to drive to Bryce and miss out on A B and C and feel like returning to hit some places U missed last time. then again it means more driving.
There are other places in states u can go without knowing how to drive. U can visit NYC, DC, Boston, Philly and up to Montreal/ Old quebec city and Niagara Falls. U can fly or travel on a train (
Amtrak - Reservations - USA Rail Pass - Select Pass) to these places. may take longer time but he don't have to drive. then again 14 days with traveling time U get like 11 days. shopping in NYC under usd$110 is tax free.
