I am considering buying access to the Frankfurt lounge near the Z gates. My flight (LH462 to Miami) has departed from the Z gates for the past 7 days as I checked daily.

My questions are:
– If I buy lounge access, can I enter more than 3 hours before departure?
– Is it worth it, especially in terms of breakfast options?
– Can they deny entry without a refund if the lounge is overcrowded?

I will be there on Friday morning (around 7 am) and I don't have any status with SA.
