Great Rides !
I had bought tickets from Costco for $27.. I think that's the best deal for Valleyfair (You can also get discount coupons from BK, Cub Foods etc.)..
Many people have mentioned it's costly, but it's surely worth the price.. The roller coasters are very good & clean.. I had been to Cedar point, Vaellyfair is comparatively smaller with less number of rides.. But, this is best place for coasters in and around MN.. According to me Renegade is the best & fastest in park.. Wild Thing is longest ride in park & it's great.. We were sitting first in Renegade & Wild Thing, the wind hitting my face during Wild Thing ride was great fun! Steel Venom is super fast & scary, High roller is wooden coaster & surely great fun.. CorkScrew, Excalibur, Power tower etc. are other fun rides.. You should not miss any coaster rides!
I have 1 year old kid and I was surprised that there were so many rides for him! Small kids & moms have good amount of small rides to enjoy.. Food is costly as expected.. I had bought french fries & it was too oily! Thankfully we took home made sandwiches & water bottles.. You can also take some food along with you to save some $ & to avoid junk food.. (Lockers are available, check the map for details)
One of best thing about Valleyfair is that lines are small.. We had to wait for Renegade for around 20 mins, for rest of the rides waiting time was @ 10 mins only..
