Thanks OP, due to the overwhelming responses in favor, I've decided to spend yet another $90 on top of the $660 already spent for 4 days next week, to try hoppers for the first time in about 40 visits over the years. I'm afraid once I see what all the hoopla is about, I'll never go without hoppers again. Maybe that's why I've never splurged on them.
I called and was told to upgrade at the ticket booths. I plan to first go in Sat. to do the 7am MM. When going out to upgrade before hopping to DCA, do I have to go out past security?
