You have misunderstood my post. I was not saying that low bucket prices were not going to be available, I was responding to the query in post 94 as to whether the sleeper berths were ever sold at "sale prices", i.e. special lower than normally available prices.While your logic sounds good it's not borne out by the facts, at least for Roomettes. For the next 30 days you'll find low bucket (the cheapest possible) Roomettes available on 359 of the 400 travel dates - or 90% of the time. But I've no reason to think Bedrooms or Family Bedrooms would show a similar pattern.
