Hey, I'm getting married there in 2 weeks. (eep!!) 1- I'm getting married on the skydeck but i know, as it was stated earlier, it's always there.
2- I am bringing my own sheers and I paid for a large arrangement ($60) to be put in the center. 3- You can ask your TA for measurements, I know for the skydeck they had a diagram. 4- You can bring your own and they will charge you depending on how much there is to set up, they told us it would be a max of $250 5- We went with the free package as we had enough guests hope this helps.
