ceremony vent

so i'm trying not to get married @ the RH bc i want to take pictures at the beach and i don't want to see FH before the ceremony.

we reserved the date at the lighthouse, but that's a huge headache. i have to shuttle people either from the RH or from field 5 of robert moses and that's after i pay the state parking @ the beach for all the guests. also, if it rains, they only have room indoors for about 40 people. we're expecting 100+ guests, so we'd have to get word to everyone at the last minute if it rained of a change in location to the RH.

we reserved the date at the bellport unitarian church, which we thought initially was perfect bc it's has a beautiful lawn on the bay just like the RH, but we have the same capacity issues should it rain; we can only get 75 people inside. we also have to rent porto-potties no matter what. it would have been perfect bc we want to make FMIL's house in bellport the 'center of operations' so to speak, and planned on having drinks/light snacks at her house in between so guests would have somewhere to go while we were taking pics.

i need an option that's not going to have me freaking out about weather for weeks leading up to the wedding. i really don't know what to do...
