I honestly think it comes down to how you view the concept of getting up early to be in the parks and the value you see in it. There's no "right" or "wrong", it's based on your own value judgments.
We are offsite guests exclusively, so we're not eligible for EMH. But we have zero interest in it even if we were eligible. Showing up at the gates at 7am or 8am does not sound like fun to us in any way, shape or form. It sounds like torture. This past Christmas, we thought we'd surprise the kids with something different and we booked two rooms at the Dolphin hotel for just one night (we're a party of 5, so we needed two). When they figured out the surprise, they asked which park had EMH the next morning because they all said "Ohhh, we want to try EMH". I forget which park it was....it was either Epcot or HS, and it started at 7am. The kids pondered for all of 5 seconds and said "No thanks, not interested". We are very heavy users of FP+, and using that we can get on pretty much anything we want with no waiting, so EMH doesn't hold a lot of value for us. In fact, even though we're offsite guests, we don't pay any attention to what parks even have EMH. So I couldn't honestly tell you if how often we go to parks that have had EMH that morning, we're oblivious to it.
That's just what works for us. Getting up at the crack of dawn, or before, on vacation is not worth ANY ride in WDW for us.
