Spike had his crystal form during the Crystal Empire - Part 2 episode; so I was kinda expecting him to turn crystal when he, the CMC and the pets arrived at the Crystal Empire train station. However, now that I think about it; maybe it would´ve been more logical for crystal effect to start after entering the actual city.

Also, in the EG movie they had the opportunity to use their crystal forms, but decided not to use it. However, maybe it only effects ponies that was actually born in the Crystal Empire; and not outsiders like Twilight and her friends, Cadance and Shining Armor. It only works on outsiders for a short amount of time.
