lol.....my dad ran the sluice way for 2 years after he retired the first time. it's great fun, and mike deff makes sure that you'll find some stones in any bucket.
but, if you want to get the REAL expierence (non-juiced buckets and what such) just grab a screen and some shovels...and head down to the creek/river....or if you can, go up and dig around some of hte claims areas (be sure not to dig on a claim....or...yeah....that can get kinda sketch)
lots of quartz, good chance of some emerald, ruby, or other gems that are natural to the area as well.
when i was 9 or 10, i found a rutilated garnet just walking on the trail....had it cut, by mike, into a stone for my mom...who had it mounted in a ring, it was a GREAT gift.
as for staying...there's not much, at all. and you'd be smarter to stay in statesville, seeing as it's considerably closer than hickory....and still plenty of places to eat/sleep.
