Actually, getting thrown off your normal routine is a good wake up call sometimes. Being too stuck in your home schedule makes you brittle (like a seized bolt that snaps when you finally try to turn it). A break forces you to adapt, and maybe you find a ten minute walk on the beach does more for you than your usual yoga. The tight muscles you felt were probably from travel stress, not skipping stretches. Next trip, just try moving in any fun way that fits the new place instead of forcing the old plan.
