Sorry it took a little while to respond, I just joined yesterday... I brought my son to the Middle East from America when he was 4 months old (that was two months ago) and will be facing your same problem when I go back to visit in a few months. My plan is just to ride it out; jet lag is almost a sickness and I've found it's best to just give in to it. I've been fortunate in that my son naturally falls into his schedule, so when we came over he transitioned pretty well to the new time zone. It took about 2 weeks before he was "normal" and during that time I just let him sleep when he was tired and tried to keep things quiet and dark if he woke up at night.
When I go back to the U.S. this summer, I'll just do the same. You can't tell a baby that their sleep schedule will be screwy for a few weeks and expect them to understand and happily comply with your efforts to make things easier for them :-) So, I'll just let him sleep when he wants and hope he's up enough during the day to see everyone and sleeps enough at night to let me get some rest too. I know if I try to keep him awake I'll just have a cranky, unsocial, tired baby on my hands. I have heard that it helps to expose them to daylight when they are up during that time, though.
I know I wasn't much help, but hopefully things go as smoothly as possible for you. There's really no use in worrying, it won't change anything :-) I'd just face it knowing it'll probably be a little rough but everyone will make it through and will hopefully be back to normal within a few weeks of your return.
Good luck!
