I apologize for my mistake. The punctuation in "We're going to dance" is correct. It consists of a contraction of "we are" (we're), followed by the verb "going" and the infinitive "to dance". There is no need for punctuation between "going" and "to dance" as they form a verb phrase.
Yes, the punctuation in the sentence "We're going to dance" is correct. It includes the use of an apostrophe ('), which shows the contraction of "we are" to "we're", as well as the period (.) at the end of the sentence to indicate the end of a statement.
