I have been there a few times, most recently over Memorial Day weekend. Its a nice spot. The casino is not huge, but has everything you need (craps, bj, slots) and the cocktail service is swift. There is a Starbucks on site but is super slow, they also have a little bar/restaurant off the lobby and a nice steakhouse on site.
The pool is fun and they have plenty of cabanas and chairs available. Plus, they have pool blackjack. The crowd is more family and less drunks (which is nice). However, the best part of Harrahs GC is the seafood restaurant across the sky walk called TBT. Great spot for a cocktail with a great view and while we didnt eat, the food looked great.
Have fun!
