Have a great time! & yes please keep us all posted on the outside florist situation. You should find out if they will charge you an additional vendor fee for that, or if the florists could just drop off the flowers. Also, find out if they will charge you a set up fee.
We are still in the early stages & I asked about bringing in our own decor - really just some colorful flags that you see at Mexican celebrations known as 'papel picado' (kind of like those banners you see at fairs) - they are fairly inexpensive but when I asked if we could bring that in, Cecilia said it would be an $80 set up fee! sheesh - so we won't be bringing that unfortunately. So now I am looking to dress up the day with flowers.
I will also be doing a site visit in July so keep that in mind ladies if you need any additional questions answered.
