Today I achieved the most success I've ever had with virtual queue sign-up. I was up at 6:50 am, selected my group (which was just me), and got time.gov going in a separate window. At 6:59:50, I switched back to
MDE and mentally counted down the next nine seconds before hitting the Refresh button. Upon pressing Join, I was told I was in BG 2 and in fact my group was 'called' at 8:17 am, when the off-site people were still waiting to be let into the main part of the park.
I really should have used a second device for time.gov, I suppose, but that early in the morning I just don't have the motivation to make a big production out of it. For the last few minutes before 7:00, I counted ten-second intervals along with time.gov to get into the rhythm of it. I also noticed that my data connection out here (one of the new-ish hotels in the Flamingo Crossing area) was nearly a dead zone, so the hotel wi-fi was crucial for success.
