One thing I forgot to mention - Make a checklist of *everything* you think you might need. I decided to spend the night before my wedding at the hotel where our reception would be. So I packed up my dress, petticoat, hose, white handbag, jewelry, blah blah blah, and went out there the night before the wedding. We had our "night before the wedding dinner" (not really a rehearsal dinner b/c we didn't do a rehearsal - but the whole wedding party went out to dinner, and we gave our attendants their gifts etc) and went back to the hotel. Before going to sleep, I did a nervous last-minute check. Dress, check; jewelry, check; underwear, check; shoes - OH &#*@!!!

So my dear fiance drove all the way back into the city to get my shoes from our apartment, then drove all the way back out... and our wedding was a morning wedding! And he still married me
There was a term that was tossed around on those newsgroups I mentioned: "Bridezilla". For the bride who insists that every little detail be absolutely perfect - usually driving herself, her fiance, her parents, and everybody else nuts in the process. Like DeltAlum said... it's not a crisis if everything isn't "perfect perfect" - at the end of the day, you're still married, and that's what's important.
