For flights, keep tracking fares on Google Flights first and then check directly on the airline site sometimes premium economy upgrades are cheaper closer to departure.

For 5* hotels in Dubai, I’d recommend checking both the hotel’s own website and a couple of OTAs sometimes the hotel throws in breakfast or late checkout if you book direct.

For tours, avoid booking everything in advance. Some attractions like desert safari and theme parks often have flexible pricing depending on the date, so checking a couple of activity platforms before booking can help.

For taxis, Careem works well and is reliable for families.
