So sorry for your loss. I am taking my first long solo trip, after a very long time. I took one two day short trip to DL about 10 years ago, then the family joined me, I found it very peaceful, and look forward to doing it again. I have been divorced for 26 years, so why did it take me so long, well I had kids, so I never had to go alone, then I had a grandchild and so for 8 years she came, now she is in school r high and can not miss school. I am blind but I don't think that slows me down to much. Anyway this year, I just could not think of anyone to go with and I would rather go alone than not go at all, so I am going for 16 days by myself.
I am thinking now, what I really want to do for eating. I don't mind eating alone, but at Disney eating is usually to reconnect and lots of laughing family time, so I'm thinking quick meals might be betterment don't usually do to many quick service so it will be different. Also, flower and garden will be there in May so Epcot will be great for quick service food. I thought about club level, but seems like such a waste for one person, but would help with a lot of that ackwardness.
Well I wish you well.
