Will be spendinga Saturday in Aspen in late June. Planning to take bus to Maroon Bells, Silver Queen gondola, farmer's market, John Denver Sanctuary. Should I go directly to Aspen Highlands Ski area for the MB bus and then drive to downtown Aspen? Or should I park at Ruby Park Transporation Center and take the bus to the Aspen Highlands Ski area for the Maroon Bells bus tour first? Then after returning, ride gondola and walk to farmer's market, JD Sanctuary, and shops in downtown Aspen? Is this itinerary OK? Any suggestions or ideas are welcome.
