We travel a lot ... to nice destinations, and to beautiful lodgings. While Breckenridge is indeed wonderful -- even in off-season -- the Grand Timber Lodge is to be avoided at all costs.
The 'lodge' is clearly set up for skiing season -- put lots of people in the buildings, and make the rooms small and cramped to accommodate them all. The rooms themselves are poorly appointed and dated, poorly maintained (the first room they put us in had an odd fruity air freshener smell -- but as soon as we arrived, the toilet overflowed -- so the reason for the smell was evident ... this had happened before!), and simply worn out (the carpeting was stained and worn, the baseboard heaters falling apart, etc.). Though it was Fall and the weather cool, the heat worked wonderfully -- to excess, and only then did we discover that the a/c did not work.
There were many other issues -- including a garage door at closed on our car while exiting (the desk clerk said that we had an arrangement between our rental car company and us ... and didn't see how they were involved!). The parking garages were too small for the buildings, so you often needed to stay in another building. And because this is a 'lodge' -- there is no housekeeping.
Need I go on? As a timeshare this might be acceptable, but as a hotel it is not.
The final insult is that we paid over $300/night. This easily rates as one of the worst stays we've had ... ever.
