The VL on 4/16 dropped at 11, 3, and 6. Each time I had between 3 to 5 time slots to pick from, each time I picked one that did not have 2 spots open as when it would check after picking a time slot, it would tell me it was not available and I should try another time slot.
I did speak w/ someone who got a time from all three drops, they told me to make sure I turned wi-fi off (though I do not recall ever using UOR's wi-fi but I get why one would not want to use wi-fi when demand hits like it does for these drops.
Speaking to some folks that went towards the end of the night (one folks I spoke to) mentioned their wait was under 20 minutes, so it sounds like VL can be a good experience for those that win the lottery.
I should not that the drops opened (for me) a minute or two (maybe three minutes) after the hour.
