Messy - do you have a photographer? Or ate you banking on friends taking photos etc? Could you put some blank cd's out with notes for people to copy any photos and send them back to you?
I'd do as stealth suggested with jars or bases upturned or beg steal and borrow cake stands. You may be surprised who has a white china cake stand. Of my friends i know that at least four of us have one so you may be surprised if you ask around.
Your whole theme sounds wonderful and really up mine and stealths street in particular. We've been bursting to do bookish decorations. Please please put pics on your profile of the details afterwards.
Are you doing any speeches? Gifts to special people?
Messy play party was brilliant. It was going so well with kids just moving from section to section and getting so engrossed. Dh banged on the table and called out "i dont think its fair to pull the kids away to eat around a table, so grab your food and keep playing!" It worked so well i didnt worry about timings or cajouling dd's into staying seated etc. dd1 ended up stripping off and climbing into the washing up water sensory tub with dd2 crying "want mine bath too!"
My lovely friend got both my girls and showed them the bridesmaid dresses she had bought them. I hadnt told them and they were wide eyed at being asked to be princesses for a day to which my friend cried which set me off.
Then i got a text later from someone else saying "your parties are the best ive ever been to, the others are just crap! And you do the best party bags!"
Makes it all worth it!
