We have booked a holiday to one of the Eurocamp resorts near Efteling, and some of the reviews mention children being made to swim with armbands because they didn't have a swimming certificate.
I'm getting a lot of conflicting info about this online, from it being a height thing to them not caring, to it being really strict - so I have no idea. Has anyone actually been? Were you asked for a certificate?
DD is 8 and has a few certificates and distance badges so I could photograph or take some of that if it would help (she's in Swim England Learn to Swim level 6 but likely to be at level 7 by the time we go). She's a confident swimmer and has never worn armbands so I think they would put her off!
