Hotels for Westlife 25 - The Anniversary World Tour

Twenty-five years since four lads from Ireland became a boyband juggernaut, this anniversary run is built for the fans who grew up on their ballads. Expect a set list leaning heavily on the early hits alongside newer material, with the kind of singalong choruses that fill an arena without much prompting.

Sunday evening crowds tend to skew towards groups of friends and mothers-and-daughters marking the occasion together. There's a nostalgic, celebratory pull to a milestone tour like this that a standard date on the calendar wouldn't carry.

Set beneath its unmistakable tented roof on the Greenwich Peninsula, The O2 is one of the world's busiest indoor arenas, drawing global music tours, comedy and sport year-round. The complex wraps the arena in cinemas, restaurants and riverside bars, with the Thames Path and cable car close by. The Jubilee line reaches North Greenwich in minutes, and riverboats offer a scenic alternative. Staying on the peninsula or across in Greenwich means an easy walk or short hop back after the encore.
