But Keep In Mind....
The more options a meal plan has, the more expensive it tends to be. Some meal plans don't really break down how many per week you get. They give you a certain amount of meals and it is up to you to divide that over the amount of weeks you will be there. They are typically assuming you'll use the same amount per week though.
Before you purchase a plan, do some math. Do you want to eat three meals a day? Do you have time? Do you even eat full meals, for the most part, or do you catch a snack? Is it worth the money to pay the sometimes high food prices for college? And on the note of snacks, is there one particular snack you find yourself reaching for in the vending machine? If so, don't keep wasting your quarters; by that snack in bulk and stash it in your bag.
Check out your dining options, too. If you see a lot of food you know you're going to like, is that going to make you more likely to buy a meal? Will you over eat? See if you can try some of the food on a visit or something before committing to a plan. You don't want to pay for food that is disgusting and you will never eat. Are you allowed to take food out of the dining area? This is actually a big one, as some colleges will not allow food or plates or anything to be taken out. Also add in how likely you are to want something not available to you on campus and figure that in to your total cost of eating.
Don't be fooled by how low the cost seems at first. There are some people who purchase the plans and never use them. There are some people who never have time to use them. Remember that a lot of college dining places close at a certain time. Are you going to be able to work your schedule around that? What are you going to do when it comes to having a midnight snack? Overall, what is the cost of each meal? It could just be too pricey for you, for the quality of food you're getting, and the time constraints that are applied to it.
It is nice to have a dining plan over all; you just don't want to have to spend more money on it than you really need to. There aren't many colleges who offer a roll over plan as far as meals go. Once that semester or quarter is over, that money is gone.
