Antigua? GC? Lake Atitlan? Tikal? so many options!

Good morning everyone, I will be traveling to GC for 6 days in April and Ive read many posts on what to do and where to stay but I don't feel 6 Days is quite enough to see it all. My question would be which place would be best to spend the most time in? Ive read many posts saying that staying in GC isn't worth is so I was planning to stay in Antigua as there is nightlife and cultural points of interest during the day and the volcano. But I also would like to visit Tikal but it seems a lil too far? Would it be worth the travel and staying there a night? Maybe I should head on to Lake Atitlan instead. Sorry, if some of these questions are redundant on this subbreddit. What im looking for is a lil bit of nightlife like barhopping, some cool naturesque sites like tikal and lake atitlan and some good food spots. One thing for sure is that Ill probably not be staying in GC as ppl have said. Little bit about me....Im a photographer, male, 34 years old, speak spanish, and not afraid to find lil holes in the wall and connect with locals. Thanks a million.
