They're damned hard to mount. One issue is that the belting reduces the internal volume. Use a smaller tube size than you normally would.
I hear this all the time about Continentals but I've never found one of their tires to be difficult to mount...even the Gatorskins which are supposed to be notoriously difficult. I've helped many people at my local co-op mount the Gatorskin and never found them difficult to mount.
My biggest problem with the Continentals has been keeping them on the rim. I've had at 6 blowouts with various models of of their touring tires, including 4 in one 26 mile trip that left me stranded without any tubes. And that was with the tires all pumped up only to their recommended pressure. Kind of soured me on Continentals entirely. I've found better tires that are cheaper and better.
