I always get a camper vehicle if I am going a long distance to make a mini vacation out of it.
When I travel out of state for company I always like to travel by train! I am not a fan of having to take planes because let’s face it, it just gets way too cramped and half the time their heating and air conditioner does not work well, however on a train, or at least the ones I have been on the heating and air conditioner is great just like a hotel. I always get a camper vehicle if I am going a long distance to make a mini vacation out of it. and always experiencing superb heating and air conditioner on trains I can also say that the air quality has been good too considering what you usually would expect from traveling by train. I always will pay the money to travel this way even if the company I work for is paying for airline tickets. I simply tell them how I feel about jetliners and will not travel on them, however so yes, I have to pay extra money traveling this way, but it is all worth it just enjoy full indoor comfort from perfect air conditioner or heating along with the top notch air quality that I always acquire on a train. I would never want to trade this in for anything in the whole wide world, however if there ever came a time where the heating and air conditioner stopped being good and the air quality got terrible I would honestly just travel by plane.
