Looks like I posted in this thread a few yrs ago.
What we ended up doing was buying huge duffle bags (so big they fit a person...yes I tested it out lol) and stuffed they with the OOT bag stuff and wedding decorations. I carried on the glass vases, toasting flutes and any of the breakables but all the bags, survival kits, paper products and other goodies for the bags were in boxes or bags inside the duffle bags. That way I had my suitcase just for clothes/honeymoon stuff. It worked out great and we brought just about everything with us...centerpieces, vases, lights, sashes, OOT bags, etc. Yes we paid extra for the extra bag but that was part of the "wedding budget" so I didn't care.
Oh and remember all the crap you are packing for "vacation" you probably wont need, wear or use.
Hope this helps you ladies.
