Firstly I would like to refer you to an explicit Teshuva of the late Rav Wosner ZT”L on this subject in his Shevet Halevi (you will find the exact location in the index).
Rav Chaim Kanievsky also made it clear that people should daven all tefillos with a Minyan during Bein Hazmanim.
Secondly given the many tragedies and dangers r”l during the holidays people are certainly advised at least to do some proper davening with Minyan.
