I've never used Eurostar before, so forgive me if I'm missing something obvious, but I'm trying to book a ticket from Amsterdam to Brussels over a weekend in April and the dates are greyed out and it says "Not available" under all trains. I can't find anything about work being done or anything that might be the cause to this... any ideas? Are all the tickets sold out?
If I can't get a direct train from Amsterdam to Brussels via Eurostar, are there other alternatives that won't take a ton of time?
