dual enrollment

i want to take dual enrollment as a junior next year and i’ve already started my application process. i wanna do it in the summer but i talked to my counselor and she said that i should try doing it in school first. but by the time im a junior i’m gonna be in honors and ap classes, so i don’t think i’d have time to do that and dual enrollment classes too. should i still do it in the summer? what do you guys think?
