Denver area checking in here,have hiked most of the area on the east side of the park, and headed to RMNP with the wife and kiddo this afternoon. Snow could be a concern in October at any elevation, however the weather pattern has been so insanely dry, I would hedge and say this year the odds of wet/snowy weather is less likely.
For hikes, if you want to get away from the "typical tourist" hikes, below are a couple of suggestions.
Odessa Lake - Ideally, park a car at Fern Lake trailhead and then either take a 2nd car or shuttle to the Bear Lake trailhead to start the hike. Start on the trail to Flattop Mtn and about a mile in turn off to Odessa, and that's where you leave the tourists behind. The overlook before you drop down to Odessa is jaw dropping! Continuing to Fern Lake (where you pick the tourist back up) and then the Fern Lake trailhead makes a really nice 8.5 mile route.
Ouzel Lake - From the Wild Basin trailhead. It's nearly 10 miles round trip, but a beautiful hike with about 1500ft of vertical elevation gain topping out at about 10K feet.

In addition to the other hikes people have mentioned, Mills Lake is nice. Also, Chasm Lake always looks like it is worth the hike, I have to say I haven't been there, but the photos I see always look great. That lake will be frozen by the time you are up there.
Mills is also a nice hike, not as crowded as Dream/Nymph/Emerald hike (the quintessential RMNP tourist hike). IMO a better alternative is The Loch to Glass lake. Scrambling the rocks/falls to get up to Glass Lake is the payoff! I've done Chasm Lake and it's really something else, but parking is going to be a major issue as it starts from the Long's Peak trailhead, which in Oct won't be as crowded (which fills by 4am during late summer) but still busy, especially if it stays warm and dry.
Also check with the Ranger(s) at the visitor center before entering as they can be very helpful with suggestions and trail conditions.
If your group likes Coffee, skip Starbucks and hit up Long's Peak Coffee & Paper. It's right in Estes, but on the backside of the buildings along Main Street facing the river. You'll know what I mean when you are there.
If your group likes beer, check out the Estes Park Brewery or make the trip to Fort Collins to New Belgium Brewery.
