I will. Especially when I go back in August. My GF is so pale she's practically an albino. And I'm not exactly a sun-worshipper myself. If we can enjoy the best rides in WDW without wilting in the sun, that's just groovy for us.
Having said that, I wonder how many resort guests wind up taking advantage of the late nights. Don't get me wrong, I'm sure plenty do. But when you consider how many people are up and running at dawn because they or their kids just can't wait to hit the parks...burning the candle at both ends to such a degree as to use EMHs I think would destroy a lot of people. But hey, when it comes to WDW, people seem to find a 2nd, 3rd or 8th, wind to get back out there
