Pictures of decorated venues where you can't hang anything??

I think that your venue is a great backdrop for a tropical theme wedding with the colors (cream/sand) and the wood. I think that once you fill the room with people, your cake table, dj, buffet tables etc. you might not notice the pictures on the walls or the stuff that you don't like.

Not to be mean but I don't like the blue tablecloths in your venue photo. I think that a lighter tablecloth or even a brown overlay would look more elegant and a pop of color in the centerpieces with a few candles.

Seconding the draping for some of the historic signage. BUT, definitely check with your venue about trying to cover some of the EXIT signs. Those are for safety reasons and OSHA probably wont allow those to be covered no matter what you do. Each exit will probably also need a certain amount of space around it for free movement in order to meet OSHA and fire dept safety guidelines.

Agreed- blue is NOT one of my colors. The ginger in your photo are actually my plan for bouquets. I am more of either crip white w lush tropical greenery or the cream, greenery and tropical flowers like ginger etc. I think going with the current decor of the venue (and the genius idea of photoshopping out the signage and photos I don't like) with lights and uplights I will be fine... I am just in the typical overthinking while planning trap! hahaha

I didn't read all the way through all the comments so I apologize if this has already been answered, but can you hang/drape anything from the balcony? It would be really easy to do in a way that doesn't damage anything.

Maybe some draped greenery or garland?

There is so much you can do to dress the space up!! But I definitely think linens and lighting will make a big difference and not cost a ton. Target usually has good after Christmas sales too!!
