In your story about traveling with young kids and babies, you forgot to mention the best option — the train. Amtrak trains are ideal for families traveling with children, as there are many comfortable and convenient accommodations that are unique to train travel.
There is no need to worry about obtaining bulkhead seating since all trains have special changing rooms for parents with infants. Also available are several different kinds of private sleeping accommodations — complete with beds, showers and restrooms. There is also no worry when mealtime comes around — you can enjoy your meal in the comfort of a rolling restaurant or in your private room as well as at your seat if you are traveling coach. Long-distance trains also have a children's play room, with activities such as games and music to allow your kids to stretch out and move around while en route. Finally, one other attractive point — Amtrak offers special discounts for families: Children under 12 are half price and infants are free. Families may want to consider this alternative to carsickness and dealing with "accidents" during the meal service while trapped in the window seat of an aircraft at 30,000 feet.
