Need recommendations for hotels or dharamshalas in mathura and vrindavan

I would be visiting Vrindavan and Mathura on 8 August with my family. Since this is my first time visiting there I am not aware of any hotels or stays there can you please recommend some good family friendly dharamshalas or hotels to stay.

Also can you guys provide a list of Temple that we should visit I would appreciate it if the list is in order. Our trip is for 3 and half days .

Also is it necessary to pre book our hotels or dharamshalas.
