Morey's is definitely worth a visit!!! The Great White is a fantastic wooden coaster, it has a little bit of everything, including an awesome first drop. Its one of the most underrated woodies in the country.
The piers are worth a visit themselves because they have a huge selection of rides (probably more than 100 total, including tons of flat rides). Almost all of the piers are run by Morey's, therefore you can buy a pay-one-price and ride everything all day. Everything is well-maintained and clean, and the atmosphere is unlike that of an other amusement park.
Even the Great Nor'easter (SLC) and Sea Serpent (Boomerang) are great because they are intertwined with a lot of other rides, adding some great visual effects for riders.
