It is so hard to take vacation from our daily life and not take "vacation" from our diets too, but that doesn't have to be the case.  Someone once said to me, "Why are all our memories wrapped around food?" and it's a good point.  When I think about San Diego, I think about VG's Donuts, Fish 101's fish platter w/ Lola Pinot Noir (highly recommend), Pipes Cafe's Avocado Sausage scrambler, and the list goes on.  Do you know they estimate the average American GAINS 15 POUNDS on a 10 DAY CRUISE!??!  

And business trips aren't exempt from weight gain either!  When enjoying continental breakfasts at hotels, try grabbing fruit, egg white omelet with veggies, protein and half the amount of cheese they'd normally use.  Skip the pastries, bread, sugar ladened yogurts and juice, All that sugar will make you crash later and just adds to the fight against cellulite.  

Here are some good choices you can make at fast food restaurants while on road trips.  My favorites are Chick-Fil-A and Panera Bread.  Their salads are filling and delicious.
