Travel-rules are totally different from House-rules. Just as an example:
Whenever we're in Italy we don't have dinner until 10pm, and bedtime is midnight-1am.
After a week back Stateside, dinner is at 7 and bedtime is 9.
The only time we've ever had a problem transitioning back is if we MOVE (different house or apt) with the traveling in between. Then it takes about a month of "We're not in X anymore, love... we need to do Y now", kindly, gently, and firmly (after jetlag has worn off... prior to the time difference switch... we may well be having breakfast at 3am or 4pm depending on where we've just flown in from).
