cantoresq: “Gedolim” is used pretty loosely in the CR and in that regard you are correct, some have no respect even for each other.
But the real “Gedolim” or as you said, those who are “venerated as Gedolim”, have attained that status not only because of their gadlus in Torah and Mitzvos and Tzidkus, but also for their tremendous midos “bein adom l’chaveiro”.
Jothar: “is going away to Eretz Yisroel and staying in a hotel there the same thing, or is it better?”
I would have to say that unless you’re going with your whole family, it is not better.
And even then, you can’t compare Jewish life in Bais Hamikdash times or even in Europe to what is gained today from a Pesach together with family in your home and with your Rav. Your batteries are recharged and keeps you going until the next chag.
Of course every situation is different and needs to be evaluated. I’m only citing feelings from my perspective.
At times some of our family members will make other plans for Yom Tov (usually to be with the in-laws); their absence is sorely felt and they are very much missed by the others.
