Just found your PTR, and it really spoke to me.
I am very close with my mom, and we both love WDW as well. We went on our first adult Mom-and-me trip this past October and immediately decided we needed to go together again as soon as we could.
Reading through these pages has reminded me of how lucky I am and how great it is to have her in my life. Sometimes I get worried about losing her, because it was just the two of us for many years; we've been talking about her death since I was a kid, almost like we've tried to prepare me for it. Sounds kind of morbid, but it's what we've always done. She had a medical scare this year, and it really woke me up that she won't always be with me.
We had the best trip, and I think you had a great idea to go on this trip - one I'd probably take if something was to happen to my mom, as it is such a great tribute. I'd love to hear how it went for you, if you get the chance to write again. I hope it was great.
