flower question

So I met with my florist the other day and they told me that if I end up taking pics beforehand my flowers are going to not look good at my ceremony :( I dont know what to do- we r going (just the bridal party) to Old Westbury Gardens an hour and a half before we need to be at our ceremony place and then we still have 2 hrs before the actual wedding- should I not give the girls their bo-k??? did anyone else run into this problem? HELP
