Hi back, Alyssa, and a belated welcome to the RS forum gang!
Let me know what they tell you? The help desk had responded pretty quickly to my first report but I haven't had a peep since submitting my requested IP address 5 days ago. They'll likely ask you for that info too; a copy/paste of their directions:
"Could you please visit the following website to retrieve your public IP address: https://whatismyipaddress.com
Once you have it, simply reply with the IP address shown at the top of the page (“Your IP Address Is…”), and I’ll pass it along to have it checked. Occasionally, access may be temporarily limited by automated protections based on repeated visits or geographic filters, and your IP is key to diagnosing that."
On a side note....
I'm planning to make an attempt at the elusive underground tickets by getting up in the middle of the night in a few weeks.
Do not despair if you can't get your hands on those tickets before they sell out - usually at lightning speed - for your dates. You can see down into large parts of the underground from points all around the upper tiers - you don't even have to access the arena floor - so I personally don't think it's worth losing multiple nights of zzzzzs over! Browse some of the more recent shots tourists have posted on TripAdvisor and you'll see what I mean. :O)
