Some of the past brides have mentioned that you took your supplies on your flight with you in plastic/rubbermaid totes that were taped closed. My questions are, did the airline open any of them? Did you check them? I am concerned that if we duck tape it closed and they open it then something could get busted during travel because they didn't secure it. I don't thing we really have much that they may need to look at but we did just get a deal on travel size sunscreens and I am now reconsidering taking those. How big was the one that you took? I am thinking mid size and only one.

I know the vases will take up a lot of room. You could always buy one of those fixed rate boxes too and ship the not so fragile stuff to yourself at your hotel. We had our restaurant decorate with pineapples for our centerpeices. They were an inexpensive and easy way to not have to ship centerprices there. We had our restaurant cut them up after dinner and everyone wanted to take some with them to have for breakfast the next morning.
Good luck with everything!
