I haven't read all the posts, but I do think that when family is too critical of our children for normal kid activities that it gets too tiring and stressful and it's only natural to limit contact with them. We've had to do that for awhile until our youngest is at a better stage. This is after having some rough vacations with mainly my sister.
I love my sister and I get along with her well, but she seems to have forgotten what her kids were like when they were growing up (think handfuls at best...hellions at times). My BIL has little patience and didn't even with his own kids and doesn't now with his grandkids (my sister is a lot older than I am).
I spent a lot of time with her and our mom at WDW about a year and a half ago. Our mom was fine, for the most part. She understood the energy level of my son and saw that I was trying to deal with Jake, who is a difficult child (esp then--he's improved quite a bit now). My sister did seem to notice how Jake went with the flow a lot during the almost 2 weeks that we were in Orlando, but only noticed when he wasn't behaving.

Selective vision, it seems. Then my sister and BIL invited my whole family to the beach for a week last summer. That was fun...NOT! It was in a way, but spending time in a 2 BR timeshare, trying to keep Jake occupied, afraid that he would say or do something did not make for a very relaxing vacation. We won't be doing that in the near future.
It sounds to me like Luke is being a normal kid. Kids do move around, make noise and sometimes act up.
In my case, even when Jake was "behaving", just him singing quietly bothered my sister. What was the child supposed to do--never make a sound? I can understand not wanting to listen to screaming, but there were 3 adults (my sister, our mother, and me) and then Jake. The 3 adults were talking all the time, having a good time, but Jake was supposed to just sit quietly and do nothing? When expectations for the kids are way off base there is no way that they can please the adults.
Sorry for going off on my tangent...you hit a nerve! I'll back away slowly!
