Everything that has ever been made has had good things about them, and since for every motion there is an equal yet opposite motion, everything that has ever been made has had some bad points as well. A roadshow bus has good points to them, and they have a few drawbacks also. Let's take a look at the good aspects of a roadshow vehicle.
A roadshow bus lets you have a place for your family to sleep, to eat, to prepare their meals, private toilet facilities, bathing facilities, and conveniently can be parked near the activities you wish to engage in.
With a roadshow bus you can pack groceries from home and prepare meals that you know are nutritious, delicious, and that cost far less than dining in fast food restaurants with the entire family. If you have a picky eater in your group you can accommodate their likes and dislikes without any trouble. If you have someone with a food allergy then you can make certain that they are not exposed to that food accidentally. Your family can eat their meals when they want to and do not have to go out to eat when the nearest diner is open. They give you freedom of choice to live on the time schedule you prefer.
You will have all of the children sleeping in a room that you know is safe from strangers. You will know that should one of the children need you in the middle of the night you will be able to hear them and get to them to take care of their problems. If you stay in a motel or hotel there is a good chance the family will be split up and you will be staying in a room separate from the children.
If you travel with another couple the two couples can split the cost of renting the vehicle, the groceries, and the gas expense. This makes the vacation cheaper for each of you and will allow you to maybe stay longer, or travel farther away.
The private toilet facilities assures you that you are not having to use a public restroom behind everyone else that is at the location you are staying. You will be exposed to fewer germs because you will be able to keep your private facility clean and sanitary, like your facilities at home.
The drawbacks to these units are that they do cost a large sum of money. You can however rent them to use for the amount of time you will be on vacation and you will not have to buy them.
The rental units will come with a full tank of petrol, but you must remember to refill the tank before you return the bus. The rental company will have their own tanks and be able to refill the bus at them, but the petrol will cost more per gallon at these places than at normal gas stations.
You will more than likely have to leave a deposit when you rent one of these units. The deposit will be returned when the unit is returned.
