Thanks for the comments. I have looked at the sleep and fly and the reviews are not great, apparently can be quite noisy. So maybe not that much better than the lounge, but I guess the one advantage is that you can be without a mask, which might be worth it. I guess 10 hours may be enough time to pop outside the airport before covid that is, but now not so much. I think I’ll plan on just the lounge and see how it goes...

thank you all for your thoughts. Appreciate it..
