We used the Disney Florist for our WP decor and it came in under $300.
We had candles on the altar, a memorial candle arrangement on a pillar, aisle pillars with candles on top and petals down the aisle.
When they say "petal aisle" is $200, they mean to line petals up on the side. I originally wanted this, but I got higher prices from all the outside vendors- it's not cheap. We opted for rose petals scattered along the aisle. When the wedding day showed up, I didn't notice any of it. I am glad we hired a photographer so I actually got to see what I did LOL!
Honestly, for the price we paid Disney, we get a lot more than we had asked for. I couldn't be happier.
