Multiple SPF's. I hadn't thought of that one.
I've never been able to hold still long enough to sunbathe-I guess that's why I still occasionally get carded-so a tanning bed would also be out of the question.

I think my favorite suggestion so far (but you won't catch me with my all-natch post baby slightly overweight body doing this in plastic-town) is walking the dogs in a bikini! Multi-tasking and scaring the heck out of the neighbors! Now that's what I live for.
