I’d suggest areas such as the North West shelf (N2A/B). Mainly families, has its own entrance, kiosk and toilets. Great views. Far cheaper.
The lounges can feel much more crowded in my opinion.
I’ve been twice as a guest, and tbh couldn’t wait to get back to my normal seat. I’ve declined the invite ever since.
The service in the “lounge” was slow and I kept being given my drink in a dirty glass. Nowhere to actually sit and it was only marginally nicer than standing in the kiosk area...
