A few questions that would impact your decision: Will you have your own transportation? Do you have any attractions that you absolutely have to see? Are you willing to be further gouged by purchasing
Lightning Lane to get any "E-ticket" rides (please be old enough to understand that reference!)
If it was me, I would opt for a 4 day base. Would do Ak Wednesday and consider getting an ILL for Flight of Passage (it is really worth doing). HS is definitely the park that you want to get to as early as possible--take full advantage of the early resort entry if you can. This past year, studios opened at 9, but guests get 30 minutes early. The day I went, they actually let people in at 8. So you can make a beeline to Galaxy's Edge to do Rise of the Resistance and Smuggler's Run and get those done early.
