Congrats on your anniversary and on going to Disney.....it makes the perfect honeymmon destination!!!!!
My husband and I went last year for our honeymoon and they "happily ever after" and "just married" buttons, we had both. It's completely up to you which way you go though since they also have "anniversary" buttons. You could do the honeymoon theme and get the bride/groom ears and do it up big, but I'll warn you that EVERYONE will stop to ask you when you got married and if it was at Disney. If you're okay with telling everyone a year ago and explaining each time how you didn't get to do a honeymoon etc. then I'd say go that route since a Disneymoon is the greatest, but if you want less attention and less questions go with the anniversary plan. It really just depends on how much attention you want or mind getting. Either way Disney will make it truly special for you. Congrats!!
