No. TBH I wouldn't. My kids are also FFs and often as the mum with 3 kids I get seated up the back with the unaccompanied minors. I've had far too many convos with hosties who think they should raise the allowed age to 8. Yes mostly they can cope. But leaving them for that long with people you don't even know, let alone know how they're going to treat your kiddo if things go to poo? They don't know your child either or how to help her if she needs anything more than basic.
