It's ok- last year we had Golfland Sunsplash season passes and were planning to go there again this year but when they had a one day only 12 hour super sale on season passes and I just so happened to be working a 12 hour shift that day-they peeved me into buying Big Surf season passes.
Now-Big Surf, is a bit nicer and more relaxed than Sunsplash, but it could definately use some cleaning and care. The staff are mostly high school age and have no customer service or training-so next year Big Surf could save money on staffing and just hire monkeys or hyenas because either would do the job better than what's working there now.
If you go with really low expectations, you are going to have a great time.
The food is mediocre and pricey. The parking is free and ample. The large wave pool is nice and full of pee. How do I know? I never see anyone in the bathrooms.
The slides are average.
Again, go with low expectations and all is going to be fine.
