Not my work, besides site visits in another branch, but obviously I shoot weddings too and have been abroad in quite a few places and honestly, most of the time its literally Airport - Hotel - work - back to hotel - airport.
There is rarely any free days where you are alone and free to be "on holiday", when i went to another country to shoot a wedding I try to get there 2 days before just in case of flight delay and then leave home the immediate day after so you can imagine I would be home before I am even over the jetlag (if going to the States).
A friend of mine is constantly flying between LA and London (and many other European cities) as he works in television, even he says the novelty wore off fast, it's just airport, hotel, conference, hotel, back on the plane. Sure, he gets to travel in business class and his hotel budget are generous, but it's not really a way to see the world since you are never far from your hotel room or conference room. If you are lucky, you get half a day or 1 day free, but it's often quite a long way to go for that half a day of alone time to be on holiday. The best perk is all the airmiles and airline status he accumulated so when he goes on person trips, it helps in all the free upgrades.
I just shot a wedding in Italy, landed in Rome, the most of saw of Rome was the Roma Terminal in the center, I got a photo of the McDonald's outside there, didn't even drive past the Colosseum in the taxi.
