TOURING VACATION
This type of trip involves seeing sites either in the US or abroad. We have actually done more of this type of travel abroad than in the US (probably because we lived abroad when the children were small).
Once again, like the adventure vacation you have to plan this trip carefully. Don't overdue the sites or locations visited. Be selective and try to keep the traveling between sites to a minimum, unless your child loves spending endless hours in car or on a plane!
Once you have picked the trip destination, start by making a list of the sites you want to see. Next plot the time required for each and the distance between them. Then take a close look at what you have mapped out for your vacation. See if it really can be executed and most importantly enjoyed! This is the hard part. We have found that keeping the driving distance between sites to a maximum of 3-4 hours works well and keeping the plane trips to a maximum of 9 hours is doable. (our longest was to Greece--we managed but we are still not ready for a trip to Asia with our son--it was hard when we did it as adults!)
(Note: We are assuming that you will probably fly somewhere and rent a car. Renting a car gives you flexibility and what we call "an escape route". We avoid public transportation when we can since following a train or bus schedule might not be practical with an autistic child--you can't predict what the day will be like and you will need the flexibility to change your plans.)
Of course each child is different and only you know your child and what can be tolerated. Doing a few local site seeing activities is a good way to "try on" a touring vacation. Go to the local aquarium or a historical site near your home--use this to trouble shoot while close to home. When you are away, your only escape is your hotel room or your rental car!
