Well for starters there's already locations to farm if you have the hours (The Zone, Grotto, Snow Resort, that other place next to The Zone). Plenty have suggested an Events Tent but devs have their "priority list". Mounts, hats and other items are produced everyday so no need for those demands.
Can't remember but (Zone: 100H | Grotto: 2000H | Resort: 1000H | Place next to Zone: 500H)
