I am not sure this is the best way to have this solved, but I am very frustrated and amidst a family bereavement. I am in Maastricht, along with many colleagues and friends for TEFAF. We have just found out that we cannot get to Schiphol, or even Eindhoven or Venlo to be able to reach Schiphol and our flight at 10:35 on Sunday morning, because NS has scheduled maintenance, but has not planned any alternative services. Scheduling maintenance amidst TEFAF is very strange, but -surely- you could have a replacement of some sort to Eindhoven or Venlo, and Schiphol, particularly when the biggest event of the year is taking place?! Also, customer service was beyond unhelpful, with the person responding just saying "we can see what you see in the website, call 9292", which is what we did to find all of the above. The representative of 9292 was equally shocked as this is TEFAF week and at being totally unable to find an alternative and got the above info for us. Is it possible that such but planning occurs with no valid alternative for so many people travelling and amidst the biggest event for the province and for Maastricht -during TEFAF? The most amazing thing is we have just discovered KLM appears to have a standard service leaving at 5:00 am from Maastricht Central Station, but absolutely no provisions have been made for those not travelling with KLM as 'there is no current policy for such events'! This does not only reflect bad on NS, but on Maastricht, Limburg and the Netherlands, which is a country I love very much!
