Luckily, holding a secret as opposed to a TS has saved me a lot of heartache. My vacations are almost exclusively overseas, and I'd have no way of remembering dates, etc. My security manager informed me that the only people they really worry about regarding overseas travel are those with TS clearances. Of course, I don't MR in the true sense of the phrase, either, but I have gone to Europe over a 4-day weekend.
