We don't have our own board, so post your TER ads on the "other cities" ad board. Since you can post an ad every seven days, post one now, then once a week until you get here. I would try to time it so your last TER ad hits the day you arrive in Hawaii, So you can post additional ads 7 days prior, 14 days prior, 21 days prior, etc.  

I honestly can't say how much business you can get from posting on the TER "other cities" ad board, because I don't know how many others from Hawaii check that board, but it can't hurt and it's free. You should also utilize EROSHawaii, and since you are on P411, use that resource too, to let Hawaii folks know you will be visiting. I will be sending you a PM also with additional info. Have a great trip!
