In all seriousness... I always travel with one 10 foot "on average" extension cord in my cpap bag. I also will have one of these in my suit case.

For most rooms this is fine, gets me ports for my phone and other accessories and a place to plug in my machine.
If you wanted something lighter and smaller... I also carry one of these in my carry on.

Both of the cords I linked have built in USB ports and are 3 prong so they're grounded.
I guess I sometimes travel with 2 or 3 or even 4 cords, though I seldom need to break out more then 1 or 2. I carry a lot of electronic crap, chargers for my camera batteries and other electronics so it's not just that I want a really long cord for my CPAP, I just have a lot of "Shtuff" to plug in.
I've only had a few issues were staying at friend's places, were we wound up on an inflatable bed in the middle of the floor - were I had to get creative and run multiple cords together. Me and my wife like to travel on road trips to spend time with online friends we game with, we sometimes will get together a few times a year, when you have 20+ people sleeping over in a large town house, you need to be prepared to think worse case scenario and bring more then you really need. But this is not the norm. Almost any normal hotel I've ever stayed in, even over seas - if you had a decent extension cord maybe 2 you'd be 100% fine. If your willing to unplug something or move a nightstand to get to an outlet your almost always going to be good to go with something simple.
For fun, Keep thinking out side the box...
Rest well,
