We did this in October. We opted to take Uber from CBR to avoid bus waits and arrived at AK around 8:25am for a posted 9am opening. The parking lot was open. There was a bit of a line at temperature screen, but we were inside and heading towards FOP by 8:45am. I'm not sure exactly what time the park opened, it was already open by the time we got to the gate. When we got to FOP, the socially distanced line extended well past the bridge in an area I didn't even know existed. The CM holding the wait time sign showed a 45 minute wait. We timed it and it was about 35 minutes by the time we got to the pre-show area. Some commando people may find that to be too long of a wait, but we were satisfied with this timing. Waiting a little longer in the queue is no different than waiting at the gates anyhow.
Another thing to note is what time the parking lots open - we were told roughly 45 minutes prior to park opening. This means you can't get in via your own car or via Uber any earlier than when the lot opens. Buses will be even later. If you are driving yourself, you can arrive early and line up at the books, but if you're taking Uber, many Ubers will not want to wait much longer than a few minutes. Just logistical things to consider while you're planning.
