We splurged last year (well, kind of, we did the pay for 4 stay for 7) and stayed at WL. It was beautiful and nice and fun, but the whole time my DD5 kept saying..."Mom...WHY didn't we stay at the hotel with Buzz and Woodie?!?". Go figure. She enjoyed the slide at the pool at WL, but not enough that I would spend the extra money.
I vote EIGHT DAYS in VALUE...
