congrats, i think a vow renewal is so romantic!
the grand floridian has tons of victorian charm and beauty, they have a great concierge too, and recreational activities like the gf spa and grand1 yacht cruises. the polynesian has a fun tropical vibe, the poly luau and even some hammocks on the beach. both the gf and poly have views of the mk fireworks and electrical water pageant ?sp on bay lake. my h2b & i both loved the animal kingdom lodge on our last stay, has a great atmosphere and we loved having dinner at sunset on our balcony watching the animals. for our wedding week we're staying at the yacht club concierge, our ceremony and reception will be there too, we're hoping for the garden/gazebo view. we like the yc for its subtle seaside themed romance & location near the bwi, mgm and epcot.
hope you have a wonderful time!
