So many people are showing up with room numbers, maps, etc and DEMANDING that they be given specific rooms or areas.
That has nothing to do with the internet. That sort of thing started the moment people created language. Once the Xerox company came into being it was all over.
And Disney gives us the maps showing various locations, and they don't make us burn them before we checkout.
Whether or not a person "demands" a certain room is on their personality, not the method in which they obtained the maps.
I remember as a child in the later 70s writing away for cruise pamphlets and planning out trips (in great detail) the wonderful trips we would take (with the money we did not have) to see Macchu Picchu and so on. Dang I wish I had kept those materials...
In the '90s I spent HOURS studying Frommers guidebooks at my alma mater's library for my trip to Ireland (who steered me wrong in so many ways, LOL).
My mom in the 1950s used to do the same thing that everyone else in her peer group did with their families (meaning that they talked about it and had plans they followed) of going from Schenectady NY into "the city" to buy their new school clothes and shoes, and have lunch at certain places, etc etc. People talked about the best ways to do those things, and everyone did them.
People have been sharing tips on travel for ages.

It's up to each individual what we do with that info.
I agree with this.

I have family members who insist on discussing every bad point during their trip (usually saying, "I'm just telling you what happened!") when such things wouldn't even register on my radar after it's occurred.
I think either you log it as a minor annoyance, or it becomes a focal point. Your trip is really all a matter of perspective. No need to stress.
Being a "I'm going to tell you all of what happened" person, and being someone who has lost friends because THEY focused on the negative in my stories, I would HIGHLY recommend you try to focus on the positive they might be telling you. Because they might very well be telling you the whole thing, and you're just missing the positives.
I don't have a large obvious following in my trip reports (scads of views, though), but the people that read and comment often tell me that they appreciate me telling the good AND bad. They are able to see the good and not focus on the bad. They like the honesty.
Also try to be aware if you are cutting them off before they get to the positives, or the funny stuff. I've had that happen too, in person. It makes me appreciate the people in my life who understand me and KNOW that there will be funny stuff coming up, and lessons learned and good stories. So just be sure you're not accidentally causing their stories to be cut off at the negative part. Be sure you're really letting them tell you all of what happened.
