No matter where you stay in Estes you'll have the tourist experience including going out for so-so food at a premium. You may want to consider staying in Loveland or Longmont, both are about 25miles or so from Estes but you have a lot more options for where to stay,eat,etc..... There's also more options in regards to gun shops and ranges on the Front Range. For shops there's Jensen Arms in Loveland, Front Range Gun Club in Loveland (shop, range and you can rent guns too), Liberty Arms in Fort Collins, Liberty Arms Institute in Johnstown (shop, range and you can rent guns) Great Guns in Fort Collins (shop, range and you can rent guns). If you're into brewery's Longmont, Berthoud, Loveland and Fort Collins have some really good Tap Rooms or Brew Pubs
When you go to the park I'd suggest going early in the morning or about 2hrs before sunset for watching animals, plus they'll be less traffic too. You have to go up Fall River Road providing it's open. On the west side Grand Lake, kind of touristy but pretty cool and a nice drive over the top.
