I am curious as to what is common usage for saying this in Spanish. I'll be completely honest so don't make fun of me

, but I always have said something like, "Vamos a juntar a las seis de la mañana." I feel like this is wrong cause I feel like that is saying, "Let's join at six in the morning." So, would it just be better to say, "Nos vemos a las seis de la mañana"? Also, my friend told me that the word "reunir" could be used. I know there are probably dozens of ok ways to say this, but I just want clarification that the way I've been saying it is either ok or wrong so I can correct it.
By the way, thanks for all of the help. I am truly greatful!!!
