This is really well said. After my trip last Thanksgiving, where it was me, my 7 yo and my 69 yo parents (which meant me and 3 children), I was absolutely spent. The three of them had an amazing time, and while I did as well, I was constantly stressed out. My dad told me several times that he wishes I could relax, which was nice. But I knew that was likely going to be his and mom's last trip, and there was so much I wanted to make sure we got to do because it's such a special place for us, and we only had 3.5 days to do it, and their stamina is really poor, so I was going to maximize our trip come hell or high water.
The fact that I was relieved the day that the three of them left MGM at 4, which let me have 6 park hours all to myself, is so....wrong.
