hah thats funny, sfmm's is only 49.00 and they have a lot more quality rides and are getting 3 new coasters. i also found it funny that a ticket would cost 40$. i heard that a sf pass lets you visit any sf park but i could be wrong
SFA's is $49.99 for a 4 pack and $54 for individual so that might go for SFWOA as well. Both prices are a great deal though.
