Love LOVE LOVE Haunted Mansion!!!
My first trip to WDW as a parent, DS(then 5) was SCARED to even ENTER the place--too creepy for him/wonderfully creepy for me!! Grandma and I took turns going on it and then afterwards told DS he could sit in between us, close his eyes, and put his hands over his ears. I KNEW he would LOVE this ride like I do, but didn't want him to go if he didn't want to. After one ride of "peeking", he decided it was SO COOL and wanted to ride it over and over again. We probably ride HM at least 2 dozen times per trip now!!
LONG LIVE THE HAPPY HAUNTS!!!
Oh, BTW, Love the cemetary with dining room very close second. DS loves the Bride in the Attic!!!
