Not sure how much added value there is waking up early and getting to EWR early am to experience the lounge. Personally, for a morning flight, I would spend that extra hour or two at home, and plan to spend as minimum time at the airport as is safe (for me that usually would be arriving EWR around 9.15 to 9.30 but given that travel is on July 4th, roads will be empty so might even not get there till 10 am if not checking bags). Unless one is a heavy breakfast eater, or drinks alcohol early in the morning, or prefers to shower in an airport, rather than home or hotel, I really can't see the utility in getting to an airport early in the morning to 'enjoy' the lounge - or am I missing something? Your journey is already 23h 40 minutes, plus whatever time it takes from your home/hotel to EWR and from BKK to your hotel/home - why looking to make it longer?
