Advice for 1 day- Animal Kingdom AM / Epcot PM

Before getting on a Disney cruise, we have 1 day in Orlando: Saturday Feb. 14th. I've heard this is a busy day compared to others that month.

Not staying at a Disney resort or a place that gets us early access.

Have a 5 year old in the group almost 44 inches (but not quite). We love exploring cultures and foods.

Want to enjoy a leisurely day before embarking, not go crazy, and avoid long lines if possible.

Am thinking of going to Animal Kingdom in the morning and then Epcot in the afternoon.

Planning to take disney shuttle to park hop.

Must do for us are the Kilamanjaro Safari and Guardians of the Galaxy. No other "Must Dos" (yet, but open to suggestions!)

QUESTIONS:

Heard Dinoland is shut down, just avoid entirely?

What would you recommend at Epcot for an afternoon?

Do we need to buy park hopper tickets now or closer to travel date?

Is it worth a Lighting Multi Pass?

Any other recommendations, tips, or suggestions?

TIA 😊 🙏🏽
