I think I've bought lottery tickets twice, so it really is all fantasy...
I don't care who knows I've won, I'm good at saying "no".
I'd take the lump-sum, I'd rather invest what I want and let that money compound.
I'd gift a set amount to family and the few friends who stood by me during a hard time (so, three non-family people, the rest can suck it). May have to spread it out to avoid gift-taxes, but I'd figure it out.
I have four "charities" I currently donate to. One children's hospital (saved my son's life), one related to the children's hospital (saved my sanity when fearing I'd lose my son), the theater department at the local high school (changed my son's life!), and another theater related organization we both enjoy. Charities would remain the same, though donated amounts would go up. I also donate to an animal shelter on occasion, so I'd do that more frequently.
I would buy a chateau in southern France. It's beautiful and an easy train/plane ride to other countries for vacations.
I'd finally get a house built on my property. Not a large one, but about 1k sq feet, with a basement. The wood shop would get built as well (there is a slab, but the old building collapsed years ago). Sell current house, so this would pretty much balance out expense-wise.
I'd quit work, giving my two week notice, but using vacation time for those two weeks (coworkers like the overtime when we have to cover a shift, so that would make them happy!) Or, if they wanted, I'd give them even more OT by giving longer notice but still using all my vacation time (so two months + instead of two weeks).
I'd put a tiny home or nice RV on my parent's property, so they could use it as a guest house when any of us come to visit, or just want to stay in town overnight instead of driving home (bad weather, tired, whatever). I'd also get them a maid. And me a maid when needed.
I'd get a camper or camper van and drive all over the states/Canada when I wasn't overseas or living in the woods.
I'd pay the costs of my parent's garden (water, seeds), so that they could enjoy the gardening without any financial expense.
I'd buy the best quality quilting fabric and sock yarn I could, as well as get an awesome zoom lens.
