We buy the refillable mugs when we arrive and in the morning we have our 1st cup each, small coffee maker, and use our mugs and on going down for the day, stop in Roaring Forks for a second cup and just refill our mugs and stroll to the bus or boat stop. Wife has a cloth shoulder type bag and in they go, we rinse them out at the first park, have a wash cloth in the bag too, and when we're coming back during the day, refill them with lemonade again at the RF. Night time wife likes to meander over again and brings back 2 mugs of hot chocolate for us. We get alot of use out of those refillable mugs while there.
