Nah! You shouldn't be feeling guilty. You will have your hands full with a five year old. Tell your five year old this is her "special" trip with Mom and Dad. Next trip intend to take the whole bunch. It will be a wonderful trip for all of you. The next time around the baby will be ready to get more from the whole vacation. Please don't feel bad. The baby won't remember hanging with grandma for a bit. I think grandma may enjoy the time alone with the baby anyway.
