Broward DMV- please help

I have been attempting to change my last name at the DMV in Broward county for weeks now. There are absolutely no appointments available at any of the locations. I have shown up as early as possible and there’s already lines down the road. This was this morning when someone told me to go on Saturday at the Pembroke Pines location.

Does anyone have any experience with this and or know the best location or the best time or should I just give up have a different last name as my husband and child?
