What's the best option for visiting Waterloo and using (an unknown number of) trams / metros in Brussels? I think it would be to get one or possibly two Le Tec tickets and to use contactless for the Brussels services.
- I have an Interrail pass and am using it for other services that day, so that's Brussels – Braine-l'Alleud sorted
- Braine-l'Alleud station – Waterloo battlefield / panorama is short enough to walk
- The battlefield to the Wellington Museum is the bit where I'd expect to use the Le Tec bus
- Interrail would solve Waterloo station – central Brussels, but an hourly service and buses taking less than fifteen minutes longer means it might be worth taking a bus for that bit as well
- The STIB-MIVB contactless cap is, as far as I can tell, 50¢ cheaper than a day ticket so the former should work out cheaper
