The houston area has 3 major medical schools, and there are NO centers in Galveston, let me tell you! Closest (most desirable) was ~30 minutes from the island in excellent traffic. I registered in January, and picked my date/center in february. got 1st choice of both. About 1/2 my class waited (not sure why ???) to register until like April and were still able to get test dates in the last 2 weeks of June (most desireable here, b/c we started 3rd year July 1st). By mid-may, though, people were having trouble getting the date/center they wanted or switching date/centers. Some had to do some serious driving, involving overnight hotel stays, if they waited THAT long. But seriously, dont panic yet. You're fine. If you're worried, go get the info from the registrar or somebody who's already registered.
good luck!
