There are several ways of getting from Brussels to Paris. The fastest is probably the train, but it gets more expensive when you buy the ticket on the last minute.
My question can be really split into two:
Is there an alternative way, maybe through a different ticket operator, of buying a cheap train ticket from Brussels to Paris in short notice?
The alternative is going by Bus. What alternatives are there? Are there other operators besides Eurolines? maybe cheaper and/or faster?
Are there other options?
