I hadn't really thought about this before but I think you're right. Hotel meets for sex have a certain illicit appeal to them, and being away from the home environment with its distractions and potential risks (knock at the door, neighbours hearing, spouse/family returning) can help really loosen those inhibitions and allow you both to let rip, especially when it comes to not worrying about any noise.
I've fucked friends a few times (not often, and not for a while now) at my home, and had good times, but there have been times where having to keep the noise down so as not to alert the neighbours, or listening out for a knock at the door, have been a little distracting.
At the same time, I can think of a couple of times where I had sex with friends at their home - the last time was only a few months ago - where there was the possibility their husbands might turn up, and that seemed to give them an extra boost, the risk factor.
But yes, I do like hotel fun. I've had many particularly fun times in Travelodges.
