24 years in upstate NY and I finally visited EFWS. Good time with my wife and 8 yr old daughter. Park was clean. Plenty of friendly staff. Water clean and clear on all rides. Lines for most rides were very short (if any) - with a few 10 minute long lines.
Liked the fact I could get a bar-coded wrist band, put some money on it, and keep my wallet in my locker - rather than carrying cash around. Food and beverages were reasonably priced and good quality. We enjoyed the "resort" feel with plenty of deck chairs to rest up in. Also liked not having to feel as though someone was going to steal our stuff - just find a deck chair to put your stuff on and enjoy. Plenty of lockers and parking is just a short walk for valuables. I did get a locker - but to keep my car keys in just in case our bag grew legs, at least we'd still be able to drive home. Overall the place had a laid-back feel. The music mix was just right and for the $23 discounted tickets we got through my wife's employer - I felt as that it was a good value.
For first timers - a few tips:
Walking - you'll do plenty of walking up and down hill
Some rides don't allow footwear, eyewear or hats - so you'll be barefoot on concrete quite a bit
Bring your own towels, sun screen, good pair of sandals for walking
We look forward to returning next summer.
