Why should I go with other students as a delegation?
Cheaper and hassle-free but more importantly better. Going as a delegation is cheaper because you can share your accommodation with other delegate of ours, stay free and organised with the remainder of the delegation. More importantly, many conferences put priority upon delegations (for obvious reasons) so that you may still get social tickets whilst individual delegates are unable to :).
What should I pay?
Conference fee / Delegate fee at least, but it might also be worth-while to look at the socials they are providing :).
What is a social?
Basically, having fun and meeting other people. Many conferences have their own unique social experiences that genuinely attract people's attention, for instance I am a big fan of EuroMUN's social (Pub crawl etc.;), or the delegates' reception just by the Roman bath (how awesome is that?!) of BathMUN. You can get on with the list :).
I am a first-timer, and I don't know about the Rules of Procedures within MUN?
You should always look for the RoP of the conference you are going to, after all they are the ones determining the rules. However as a guideline, you are more than welcome to take a peek at the RoP of MUNEx last year, written by me, so that you can have a brief idea what you might be expecting :).

Surely if you have discovered something confusing, let me know :).
What committee should I go with?
Rule of thumb: the ones that you are genuinely interested in. Take a look at the topics and the description of the committee. Some committees' "special power" might be the source of motivation for instance the "veto" power in a Security Council. Watch out for the committee's concentration, what issues does it tackle? how many countries? basically just weighing up pros and cons.
Is the Accommodation covered?
Not in the conference fee. But as a delegation we will strive to get the best and the most suited deal to all delegates.
Is the Transportation covered?
Ditto, however some conference do cover transportation within the city.
Is the Dining covered?
See accommodation section, however some conference do cover lunches.
What's a Study Guide / Background Guide?
A Study guide is written by your dais (your directors / chairs) as a primary guide to the topics that you will be discussing within sessions. Apart from the contents within the topic, the study guide will also tell you what the directors are looking for from you. So it is very important and essential for you to familiar yourself with the guide well in advanced before the conference!
Position Paper? What is this?
Don't get it? Read the term again! (just kidding)
A position paper is basically a paper that reflects your position under a topic. By that I meant, your country's position. Why do you think that the topic is important or not? How would your country contribute to solving the issue? How would your country go about and enhance international cooperation between your aliases? etc. At the end of the day, it is not a gigantic essay or even a book, just a one(sometimes two)-page(s) document.
Oh, and read the study guide.
