I'm really enjoying your solo trip reports, great job!! Wish I had discovered these boards sooner, as I was also on a solo trip May 3rd-6th and we may have crossed paths at some point or other during our visits. I did DTD mostly that Tuesday, but then popped over to Epcot to ride Soarin' and Living with the Land (my fav). And while it seems some members were at Jellyrolls on Tuesday night, I was at ESPN Club having fun picking on Celtics fans (GO HEAT!!).
I also did the Behind the Seeds tour and really enjoyed it, didn't get to taste anything they grew, but did spot Epcot spelled out and played with some plant at the beginning that closed up whenever it was touched.
Also found the hydro gardening part very interesting and was the main reason I took the tour (last year I purchased a book on it but the year was hectic and didn't get a chance with my Mom's sudden passing).
Congrats on your weight loss, and my thoughts are with you regarding your Dad, I went through several years of being a caregiver to mine when he was diagnosed with AZ. It is not an easy journey.
Oh, and you WILL make another solo trip, I made my first one the same week in May 2010.
