Dear lord, Honeymoon in a post Virus world?
Well, things aren't too horrible. Due to massive depopulation, its going to be like Europe just after the Black Death.
The bad, lots of pestilent bodies to dispose of.
The good, rapidly decreased population led to the Magna Carta, Enlightenment, and lots more resources for the survivors.
Depending on the number of people who lived through it (and judging by the breakdown of air travel and hotel chains, I'd say over 50% mortality rate at least) and where (as well as who) the survivors are, your options would likely be:
1) Road trip.
Nothing like going cross country on the now deserted highways in a covertible, wind in your hair, running over rotting corpses as you celebrate being alive and try to spot cool stuff to loot/bring back to base.
2) Build/Steal your own pleasur palace.
After the virus, some famous land marks like The Playboy Mansion, The White House, etc. are probly now VACANT! After tossing out a few dead bunnies/interns (and fixing the utilities), and you and your loved ones can enjoy the cosy ambiance of pre-collapse society's premier locale attractions!
