There are several ways of getting to GR. If you want to fly, Gerald R. Ford International is located at the end of 44th Street and is well-serviced by many major airlines. The Pere Marquette runs daily between Grand Rapids and Chicago, and Greyhound goes to several locales in the region as well. Unless you're visiting relatives you should probably drive as West Michigan is very car-oriented.
Although the GRATA busing system runs fairly efficiently, it doesn't service the entire metro area. It's usable, but a pain. Unless you plan on staying within the city limits (and why would you want to do that?) you're much better off driving your own car.
This was very confusing the first time I heard it. A michigan left... uh... how are the lefts here different than any other left I asked? Well, when you're on a main road like Beltline Ave, there are several intersections where you cannot make a left. In order to make the left... you have to pass that intersection and then make a u-turn to go back to that street where you will make a right. It seems like its kinda of silly... but considering that there isn't as much traffic here as where I'm from, it makes sense. They don't want to slow down the traffic on the main roads by having the lights turn red so that people can turn left onto another street. By making use of the Michigan lefts, they can keep traffic on the main roads flowing smoothly and those who have to make lefts can do the Michigan left.
Grand Rapids is fairly easy to get to by plane. The airport is within the city limits, and is fairly well served by 8 different airlines, including connecting & direct flights by just about all of the majors...
Security at the airport is tight for a smallish airport - there's a guard as you drive up to the terminal building that checks every car, and the security is always on patrol. Parking is cheap, and there's the usual array of rental car companies waiting to ring up your credit card.
Surprisingly, the airport is named in honor of former president G.R. Ford. It really is surprising when you consider that most of the landmarks in this city carry the name Meijer. :-)
I go by car, it takes about 8-9 hours. i go through Minnesota to Wisconsin, then Illinois, Indiana and finally Michigan.
car for sure.
