Volvie,
If your point is not that going to a hotel is necessarily a sin, what is your point? Seriously, I don’t understand what the point of telling people that what they do is a bad bad idea. You said its a bad bad idea. What does that mean? Are you a posek and you’re saying its not permitted by halacha? If not, maybe you should keep your opinion to yourself, and maybe in general, we need not have discussions like, what does everyone think of this particular thing that some people do but I do not. Every discussion here, why do some people have cleaning ladies, buy labels, take vacations, wear sheitels, go to college, wear a colored shirt, eat this hechsher but not that one, lay tefilin on an airplane, go to concerts, go to rallies, wear a hat, wear a jacket. Its a constant stream of putting people down. Yes, we are all responsible for each other. Putting people down is not the way to help.
Yes, if someone would like to say maybe I’m just not at high enough a level, go ahead.
So, that’s my first suggestion, stop saying things like that, that what other people do, for reasons you have no idea about, and which are halachically permitted, are bad bad ideas.
