We are married couple, I'm 50, he is 59, no kids so we have more flexibility. We are both good walkers. When I went in 88 I was solo, was going to join up with brother and niece but they canceled. I flew in from Wisconsin in early Feb with a backpack, tent and sleeping bag and set up at fort wilderness campground. The cast members seemed a bit amazed but everyone was very nice. Had a five day stay and four day ticket, 2 at epcot and 2 at magic kingdom. Last day I went canoeing and visited discovery island. It only rained a little during my stay. This was before AK and HS were open. Had a blast, got to ride everything as many times as I wanted and felt quite safe at the campground by myself. Even got to eat at marrakesh and coral reef. Also ate a lot of granola bars. Would do it again if I go back by myself sometime.
I'll decide on plane tickets once I see what all this overtime amounts to after taxes. 4:20 is when later flight gets in, would probably get to epcot by 7 or 7:30, enough time to do a couple low line rides, eat and watch illuminations.
