Hi. I acquired a PP with my Amex Gold and plan to use the Aspire Lounge at Heathrow T5 in December around the Christmas holidays. I'm guessing it's going to be mad busy and I should probably prebook (I am ok with ponying up the £6 fee) but what I want to know is, will it be too busy to really get any benefit from it? Or am I just better off roughing it out in the terminal.
