Planning a vacation on your own is already challenging enough, but what happens when you want to take a group of friends on a cruise? Spring is coming, and that means that the travel season is just now heating up. Of course, it's going to still be a few months before you hit the peak of the season, which means that you can still find good deals. However, the time to start is now if you're really thinking about how to plan a group cruise vacation without stress. Even though it might not seem that way right now, it is possible to really have a great time when you're trying to plan a cruise. You don't have to live in fear of messing things up and ultimately creating a vacation trainwreck that everyone will remember for a long time to come. With a little forward planning, it is possible to create a very rewarding vacation -- you just need to follow a series of steps to help get you there.

As always, we're here to help -- here's what you need to do:

First and foremost, you will need to think about who will be attending the cruise trip within your group. This is a very important question to ask because it determines how the format of the cruise will be. For example, if you aren't taking children along, you can choose a more adult-focused cruise than someone that's taking along a group of five children. If everyone is looking to try to build a couples vacation, then you will need to make sure that everyone is pretty well matched -- your single friends might not want to go, and that's okay. Not every cruise will be pleasing to everyone. If you're stuck for ideas, you can always poll the group and make sure that you're really catering to as many interests as you can.

From there, you will need to think about the cost involved with your cruise here. The cost of cruise ships and traveling on them have gone up considerably, but there are some ways to cut costs. You can put more than two people in a cabin, which means that the cruise ship will give you a discount. However, it could make things a bit cramped, so you will need to step back and really think about whether or not you ultimately want to do this. It's one thing to save money, but do you really want to make people uncomfortable?

You can also control costs through smart booking -- for example, if you're thinking about trying to get the best deal and you want to be a risk taker, you can wait up to two months before the cruise is set to sail. This is the time to get super good deals, but you run the risk of the cruise ship filling before your group gets a chance to go.

Of course, you can flip the equation the other way and have the trip booked about 10 months in advance. The earlier you can book, the more money you will save because the cruise ship knows that you are a "sure thing" that they can count on. However, your group might want to still look around while they try to figure out what type of cruise vacation they actually want. You will need to make sure that you stay in constant communication with your group.

The length of your stay will determine your costs as well -- some people like short "weekend" style cruises that let them see a new location and then head back home. However, other people like longer cruises -- some up to 2 weeks long. You will need to make sure that the cruise lines up with everyone’s schedule, or you will have cancellations.

Speaking of, it's important to lay out some ground rules. You don't want someone to wait until the last minute to say that they can't make it, and then you have to make up that money anyway.

Overall, it's a great idea to go ahead and go on a cruise with a group. You'll have a built in social group, and everyone will be able to share memories over the great vacation you had for a long time -- what cruise trip will you build for your friends?
