There is an easier way to avoid RYR's fees without hassle, just dont use RYR. Simples.
That's all fine and good. However, it is not always possible. I am no huge fan of FR, and would much rather travel 'full service' if it's viable and not too expensive.
Sometimes it is a choice between going with FR direct or using alternative methods of transport! On an upcoming quick trip to Germany (BRE) I can pay £50 to travel with FR, £210 with KL (via AMS), £220 with BA (via LHR), or £250 with LH (via FRA). I cant really afford the other three , it's a choice between the ferry/car or FR. FR anyday....
At least you know FR is generally reliable which is more than can be said for BA this summer!
Just get a prepaid mastercard to avoid fees (available worldwide). Simples.
