I've been told that the bridal headband ears are approx $17 and the groom's hat is around $14 (both plus tax) and can be bought at DTD.
I've also heard that you can get them from ebay and thelaughingplace.com (?) but are more expensive.
Also, if you go to guest services in the park, you can ask for the free pin for newly-weds/honeymooner's.
some brides have had special treatment with the ears on and some havent. the general concensus on here is to not go expecting anything, if you get extra perks, great, but if you go expecting things, you may end up disappointed
