Thank you so much!

We arrive on October 28 and so far I have booked 4 nights at Marriott Breckenridge from October 30 to November 3 (3 days cancellation). What I was thinking was to take one night in North Denver or nearby and then head into Estes Park staying at the YMCA and then use TRR to cross to the West side, stay at Winter Park for a night and then get to the Marriott at Breckenridge.

The problem with YMCA booking is that it's not refundable bookings so I would have to wait until pretty close before booking to avoid penalties. I might just book a night in Loveland (Boulder) to head straight in to RMNP from there.

I did Bryce 2 nights a couple of years ago and I got hit by elevation sickness (Thank goodness it's only me) with loss of appetite and severe headache. Then I passed out when we got to our hotel at Torrey and I felt ok the next day - I had no idea what it was until we came down to around 6k feet.

We stayed in Springdale for a night before heading up - wasn't really aware of elevation sickness. It didn't hit me until the second night at Bryce. We learned the lesson and definitely will use some time to acclimate before heading up.
