Travel Agenda: Green London; National Cherry Blossom Festival; Bern; St Regis hotel in Bangkok; Museum aan de Stroom; Global Hotel Alliance

Today: Get your hands on a copy of Green London, Enjoy England's and Green Traveller's new map that lists environmentally conscious places to stay, eat and visit in the capital. The map is also available to download ( enjoyengland.com). Also in the capital, good places to watch the Boat Race are the Bishop's Park in Fulham and Furnivall Gardens in Hammersmith, where big screens and beer will be on tap. More Spring celebrations surround the National Cherry Blossom Festival in Washington DC, with parades, fireworks and street festivals ( nationalcherryblossomfestival.org)

This week: Get a flavour of the Swiss capital, Bern, and the rest of Switzerland at Harrods in London from Thursday to 30 April: chocolate and cheese tastings, a model railway and upgrades on rail passes ( myswitzerland.com/harrods). On Friday, the St Regis hotel opens in the financial district of Bangkok ( starwoodhotels.com).

In the diary: The big cultural event in Antwerp this summer is the opening of MAS – the Museum aan de Stroom – on 17 May. The dramatic new structure will open complete with a two-Michelin starred restaurant, 'T Zilte, which moves from a smaller venue in the city, and what is claimed to be "the largest museum collection of port cranes in the world" ( mas.be).

Finally, a new hotel loyalty scheme, the Global Hotel Alliance, is offering guests reward points across a range of groups, rather than the traditional single-brand scheme ( gha.com).
