Have you tried putting your toothbrush and toothpaste in the shower? I’ve struggled with brushing my whole life and this is the only thing I’ve ever tried that actually worked. I also put a brush and paste at every sink but the only time I can ever actually manage to brush is in the shower.
My parents used to take us to Florida in January in the 90s. It was nice and not crowded, including Disney World. It’s probably not the same anymore though.
