LSAT Test Day Preparation
Walking into the testing center can be intimidating. I'd recommend driving there tomorrow, the day before your test, and checking it out. This will allow you to become a bit more familiar with the testing location and ensure that you know how to get there. Time yourself while driving to get an idea of how long it takes to get there.
Prepare your one gallon zip-lock bag the day before your exam. Include some nice new pencils, a snack, your wallet, keys, your ID, your admission ticket, some quarters for the vending machine, your analog wristwatch, and whatever else you might need, so long as it is allowed by the LSAC: http://www.lsac.org/jd/lsat/day-of-test.asp
Wear layers so that you will be able to adjust and make yourself comfortable at any temperature.
Leave for the testing center 30 minutes before you think that you need to. You don't want to have to expend any mental or emotional energy just getting to the testing center. Allow yourself plenty of time so that if you happen to get stuck in traffic, pulled over, or otherwise delayed, you will still arrive on time.
Eat a light, healthful breakfast. You will need the energy. Don't eat anything too heavy or anything that might upset your stomach.
Don't drink too much water prior to the exam.
Be aware that you will be standing in line and then sitting in a room listening to instructions for up to an hour or two. Be mentally prepared to maintain your drive and focus throughout this period.
If you have a bad section, assume that it is the experimental section. Don't allow the consideration of any other possibility until AFTER the exam. Don't allow a difficult section to affect your performance on the rest of the exam.

Should I Prep The Day Before The LSAT?
I think this question has to do with personal preference. Most people will tell you to take the day off and relax... While this is probably the best advice for the majority of test takers, I generally believe that such blanket statements as "Don't study the day prior to the exam" are intended for the average test taker. If you are trying to get a 175+, then you aren't the average test taker, and you should remember that. Taking a prep test the day before the exam might be a good practice for SOME people. Sure, you wont LEARN anything that day, but it may help calm your nerves and keep up your sense of pacing. I always noticed that if I took the weekend off, I'd never perform quite as well on Monday. My sense of pacing would get thrown off by a few seconds per question and I'd end up missing one or two questions near the end of the first section that I took. Sure, you don't want to be burnt-out, but you don't want to be rusty either. If you usually score a 175 on Monday after taking a couple of days off, then score a 177 on Tuesday, and a 178 on Wednesday... then perhaps taking a day off prior to the exam isn't such a great idea for you. If, however, you find that you get burnt-out taking exams on back-to-back days, then take the day off. Again, the important thing is doing what is right for YOU, not for the average test taker.
Personally, I took the day before the exam off, but then that freaked me out so I woke up early on the day of the exam and took 2 full LR sections to warm up.
Today is all about getting yourself mentally prepared to walk into the testing center tomorrow and CRUSH the LSAT. Make sure your head is in a good place, so to speak. Do whatever makes you feel comfortable and prepared. If you are comfortable taking the day to relax, by all means do so. If taking today off is going to cause anxiety, then don't be afraid to work some problems out. Either way, stay away from alcohol, television, and anything else that will stress you out or dull you down. Get your head in a good place today, whatever that may take.
