A two-night Doha stop on the way through to the Maldives. The case for it is that Doha is short and concentrated — you don't need a week to see the city — and Hamad International is a noticeably easier transit airport than DXB.
Pacing
Two nights is enough. Stay in Msheireb or West Bay. Souq Waqif for the evenings, the National Museum of Qatar for one half-day, and an afternoon at the Museum of Islamic Art (free entry, exceptional building). Skip the malls.
Booking notes
Qatar's official Stopover programme bundles a Doha hotel night for 12+ hour transits — paid, starting around USD 14 per person per night for a 4-star, up to luxury tiers with breakfast included. The Malé leg from Doha is roughly three times daily, so you can build the Doha portion around any practical schedule rather than working backwards from a single departure.
