Nice suggestions. I've done most of them! 
Me too, except this one:
A new attraction nearby is the Bliss Dance Statue in the Park, an area of shops and eateries adjacent to the Monte Carlo.
...drive over to Sam’s Town and see their Mystic Falls Park filled with animatronic animals.
Well, technically it's a bit sparse right now as the bear has been MIA for quite some time. There's a nice hole where he used to be...

These attractions are free as long as you can tear yourself away without purchasing any chocolate treats.
In other words, it'll cost me 30 bucks and 10 pounds -- and those pounds aren't sterling.

Thanks for the report. It's always good to have a checklist for new visitors.
