10-day trip to Cartagena in January (with kids)

Hey everyone, planning 10 days in Cartagena's Walled City in Jan 2027 with 3 adults (mid-30s) and 3 kids (4, 3, and 1). We’ve spent a month in Colombia before and travel a lot with the kids (Jamaica, USA, Japan, Portugal, Mexico), so we aren't too worried about the heat/humdity/hustlers/"scams" etc but we'll obviously take precautions. Main thing is we travel slow hence 10 days in Cartagena when most people only stay for 3-4.

What do you think of this very loose itinerary:

• Day 1: Land at 245PM, Uber to hotel, Exito grocery run + pool
• Day 2: Centenario Park AM, pool, Plaza de Trinidad PM
• Day 3: Walk around (I mapped out some pretty areas for us to check out)
• Day 4: San Felipe Fort AM, pool, Baluarte de Santo Domingo for sunset
• Day 5: More exploring the pretty streets
• Day 6: Aviario Nacional + Playa Blanca
• Day 7: TBD (might just relax---maybe visit Bocagrande?)
• Day 8: Rosario Islands day trip
• Day 9: Relax + prepare to leave
• Day 10: Flight home at 345PM

Trying to balance sightseeing with chilling and random explore (my fave thing to do tbh). Open to any low maintenance activities you'd recommend and 100% need tips on any bars/restaurants (kid friendly and just for adults) please and thanks 😄
