When I have week-long business trips I try to rearrange my plan such that recovery week coincides with the trip. I’m then able to do the endurance spins that TR recommends.
Hilton Hotels in the US have recently gotten Peletons in their gyms. The subscription isn’t always up to date but, when it is, you can take a class or at least do a scenic ride. BikeTheWorld on YouTube has decent cycling videos to pass the time, too.
If the hotel doesn’t have a spin bike or Peleton, check to see if you can use a local YMCA or gym. Most will offer day or week passes.
