Traveling with friends and family is a great way to go. Here are a few perks of the buddy system:
Splitting the Cost– 
There are many places that give discounts to groups. Look for specials on “buy one get one” type deals. Expenses like gas money, hotels, food, etc. are cut significantly when you share the burden. You’ll find that you can save a lot of money if you travel in groups and keep your eyes open for discounts.
Enjoying the Company – Make sure that you travel with people you are close to: good friends, siblings, etc. You want to leave the trip liking them as much as you did when you began. If you choose the right partners, traveling with friends will be even more fun than traveling by yourselves. You’ll make lots of memories together and strengthen your friendship ties.
Built in Baby Sitters – You can offer to cover some of the cost of the trip in exchange for some time without your kiddos. Grandma and Grandpa are great at this. They want to spend time with those babies anyway. If you have people who you can trust traveling along side you, it makes it easy to have a romantic get away right inside of your family vacation.
If you travel with another family, your kids will have buddies as well. It also makes it possible to help each other out.
Taking Turns – Your destination might be as child friendly as they come but there will always be things that little children can’t do. Take Disneyland as an example. It’s a kid heaven and yet you must be “this tall” to ride some of the rides. If you and another family travel together, one couple can be riding the tea cups with the kids while the others take on Space Mountain. When the kids have to go to sleep you can shift whose night it is to take them home and put them to bed. By taking turns, you won’t feel guilty asking for babysitting favors. This way, you all get to spend precious time with your little ones but you also get alone time with your spouses. Whoever said you can’t have your cake and eat it too?
