Wesaysoland is a sprawling, corporate run family amusement park and the primary setting of the fourth season Dinosaurs episode "Variations on a Theme Park."

Wesaysoland was built and owned by WESAYSO as a magical way for WESAYSO employees and their families to take advantage of the newly instituted "vacation," and to spend money. Their target market is the young, the young at heart, and according to B.P. Richfield, "fat worthless tubs" like Earl Sinclair and Roy Hess. The family entertainment park was created in a single day, following the institution of vacations, through imagination, ingenuity, and a relaxed attitude towards building codes.

The park is a wasteland of unfinished rides, expensive concessions, and cheerful corporate mascots such as Moola the Cash Cow. Television in the park's hotel is limited to a stream of infomercials, all featuring B.P. Richfield, extolling the virtures of Wesaysoland.

The park is a thinly veiled parody of Disneyland and Walt Disney World.
