Amsterdam is easy to get to from both the UK, the rest of Europe and the US.
Schiphol Airport is a short 15 minute train ride from the city centre and
and unless you're arriving on Saturday morning don't bother with a taxi, as
you'll get stuck in traffic.
Book your air tickets as soon as you can as you'll miss out on
cheap deals if you leave it too late.
From the UK we've flown easyJet, BMI, Thomsonfly, Scot Airways, KLM and BA
and all have been fine. Normally cheapest by far is Thomsonfly scheduled service from
Bournemouth and of course easyJet provided you book well in advance.
