A good question.
A local answer.

Check the council's current event locations, transport changes and road closures before booking. A hotel view does not guarantee a view of fireworks.

Plan the trip as two legs if a city stop is important. That makes the itinerary clearer and lets you choose a Brisbane station close to what you want to see.

Check the current public transport planner for the sanctuary's exact entrance and your Broadbeach stop. The return stop may be across the road or on a different street.

If quiet pool time is essential, ask the hotel about adult areas and likely busy periods. Book a refundable rate while you compare current availability.

Split the stay if both places matter: changing base once is simpler than a long return day trip. Compare accommodation by the beach and evening atmosphere you prefer.

Look for a property beside established garden or bush habitat and ask the host what species guests commonly see. Sightings depend on season and weather.

Use the current Translink journey planner from your exact Surfers stop to your Brisbane destination. The trip generally involves a local connection to rail.

Do not schedule the zoo between consecutive theme-park days. Keep one flexible rest day, and compare a multi-day park pass only after choosing which parks the family genuinely wants.

Compare the current attraction list and height limits for both children, not just the park brand. One park may suit a mixed-interest group better on your dates.

Compare the exact room, pool and beach access at each property, then map your likely evening restaurant route. A beach resort can feel more self-contained.

Compare the total cost and time to the exact cruise terminal, not only the flight. The final terminal transfer may need a taxi or booked car after public transport.

Check whether the beach has conditions suitable for a toddler; a nearby calm water play area may be more useful than an ocean view.
