Iam planning our family's vacation for june next year, and we can't wait to go. is this punctuated correctly? am i correctly adding a comma before the conjunction "and" as this sentence has two complete sentences?

Yes, this phrase is well punctuated since the comma is before a coordinating conjunction that links two independent clauses.

An independent clause is a unit of grammatical organization that includes both a subject and a verb and can stand on its own as a sentence.

i don't see any questions on your profile, currently, but i'd be happy to try and with any problems that you have, so long as i understand the problem myself.
