Idlewild is an amazing amusement park geared towards families. It was actually voted the #2 best family theme park in the world. I was just there again over Labor Day with my niece since most of my family is still located in that area. We take her a few times a year and have actually purchased season passes and starting next year her two twin sisters will get to experience Idlewild too. Funny thing is that I used to work there when I was younger!!
Here is a basic breakdown of the park:
Story Book Forest --> If you kids are into fairy tales and storybooks then you must walk thru SBF. There are people there dressed as the characters and you even get a lollypop from the captain of the good ship Lollypop. There is a lot of walking around done in SBF and some of up is uphill just to be warned. Oh and a word of caution....you MUST walk thru the gift shop in order to leave SBF. Good for kids of all ages and can definitely be done with your family.
Jumpin' Jungle --> This is geared around a giant tree house with lots of little activities around it. There is a ball pit that your kids and play in, a big slide, a net to climb, etc... I actually think that JJ is geared toward a little order crowd. Not many activities that your 15 month old would be able to do there.
Hootin' Holler --> BEST food in all the park is sold at the kitchen in HH. Great prices there too. You can get hand cut potato fries and 3 big chicken fingers for under $6.00 there! There are also some shows that are performed on the stage in HH and the kids like to dance around to the music. There is a general store there and a few rides (older kid rides). Fun place. Oh, and you can also catch the train over to Racoon Lagoon from here.
Old Idlewild --> mostly the grown up rides of Idlewild ranging from the Rollo Coaster, The Spider, Bumper Cars, The Whip, The Ferris Wheel, The Round Up and The Wild Mouse. Plus many more. Your 3 year old will be able to ride these rides with an adult. However, your 15 month year old will not be able to. There is also a main stage in Old Idlewild where shows are put on by Idlewild employees. There are also lots of amusement park games here too. Oh...make sure to try a Cyclone while you are there!! Yummy!!
Racoon Lagoon --> Kiddieland in other words. Both of your kids will be entertained for hours here. Plenty of rides for them to enjoy! Also a small stage that has shows throughout the day and don't forget to take a ride on Mister Roger's Neighborhood trolley.
Soak Zone --> a HUGE waterpark that can be fun for all in your family. There is plenty there geared towards the kids. Definitely lots of fun and a must do if you are at the park during the summer months.
Please feel free to ask me any questions....I know tons about Idlewild and will be returning again in October for Hallowboo. Hope this helps.
