Your kids will LOVE Pop Century! It is a bright, colorful, fun resort with clean rooms, lovely landscaping, a large food court and gift shop, and buses that run from the resort straight to the parks, no stopping at another resort to pick up more people.
We are two mature adults and love staying at Pop. I wish my grandkids lived closer so I could take them to visit WDW on a regular basis - we'd probably stay at Pop every time. Go to allearsnet.com and click on Accommodations, then scroll down to Pop Century Resort and check out all the great pictures and fact sheet. There is even a lovely lake behind the resort, which the other value resorts don't have. Have fun!
