I will be flying from London to T4S in Madrid - Landing at 2359 and I have a Shengen connection at 720am from T4. I will be in Business class and I am oneworld silver.

I understand that there is no option for me to enter any lounge during the night, is that correct? If this is correct, where do you advise me to spend 4-5h in T4/T4S?

Thanks for your help !!
