So, it's decision time!
Based on dannyboy's suggestion, we'll head to "le Charly's" at rue du Lac 45, Vevey, which is about 500 metres or so from the station (
map link). The consensus appears to be that Thursday would be best, so lets do that: Thursday 29th (Mar' 07) at 8pm. SamC and I already know of the change, and the only other firm 'yes' we have is Rameen, so I'll send him a PM to let him know about the change.
Heather and I will plan to take the 19:33 train from Lausanne, platform 3, arriving in Vevey, also on platform 3, at 19:51; if anyone wants to meet us on that train to then find the bar together then they are welcome to do so.
