We booked at Sydney Airport Rydges for the first time on our last International trip a couple of months back, and are booked again in a few weeks from now and already booked for next July.
I typically book a refundable room with the food and bev credit, and look at it as a couple of free drinks and a snack the night before we fly. This time the sleep, dine, fly package. $235 I think for the night, in an airport view room. So we can hang out, watch some planes from the room, have dinner in the city, take the train back and have a nightcap at the hotel ("free" thanks to the $35 - $50 food and bev credit, plus my free members drink, which the bartender actually comped 3 for my last stay) - I find there food average though.
With 1 minute walk to check-in, I never have to worry about airport traffic. Example, for our 1215 departure on SQ, we would need to arrive at 915 to be 3 hours early. That means on a NORMAL day, I need to leave at around 730 (we live in the Southern Highlands and have to take M5), if we park on-site, otherwise add more time. Say we park at our friends in the inner west and uber to the airport, now we are leaving before 7... Peak hour on the M% and the tunnel = an unhappy camper.
I like to arrive early, stroll through the airport, browse duty free, get my GST refund, etc.... If we hit big traffic, the time could totally blow out, and my blood pressure would go through the roof...
Not having to worry about the drive, etc. and no last minute packing, makes the night before the holiday so much more relaxing, I sleep like a baby, and get an extra 2+ hours of sleep, and don't have to worry about losing any F lounge time.
