I'm starting in January. When is the wisest choice to go to Dominica and have enough time to look for apartments? If I get there a week before school starts, will that be enough time to find an apartment near campus?
Has anyone heard about 110V apartments allowing for plugged in clocks to work properly?

110 volts won't help on plug in clocks, they use 50 cycle. That can't be changed. Get a clock that runs on batteries

One week is more than enough time DO NOT COME any earlier..you will be miserable because NO ONE else will be here. There is a good housing tour that the school offers. Take it. Also, when you first get here don't be too overwhelmed...take everything students say with a grain of salt...remember a lot of rumor fly around so try and get everything double checked. You will be fine and good luck. PS get a battery alarm clock...also the nokia cell phone people get here have a pretty loud alarm clock on them if you decide to buy one.
