Sorry that six flags didn't work out.
Disney is a dream esp in off season.
Wait until you are fifty and go on a simple ferris wheel with seats and foot rests that seam to shrink the higher you go. You'll feel happy your kids are grown by then.
I think your river trip seemed so tranquil and even more so memorable.
Thanks for sharing your story.
( sorry for the oneliners but I just woke up)
