Yes it is VERY crowded, especially from Wednesday on.
First week of December is much less crowded and the weather is similar. Average highs are in the mid 70s with morning lows in the mid 50s. But you could get some days in the 80s or some days staying in the low 60s and mornings in the 40s.
Only TL will be open at that time, BB will be closed for rehab.
