Best time for summit one

Hello

What is the best time of the day to visit summit one? I am sure once it gets dark it may be no good. A lots of people here are suggesting sunset times. Would that be the only good time during the day ? What are the other good time to visit it on a Saturday

We are planning to go there first weekend of May.

How far in advance should we book? I know everyone says to book just a couple days in advance - would it be such a bad idea to book it a week in advance? Isn’t this time of the year relatively dry? And for now it is definitely showing as a dry Saturday …

Or should you strongly suggest to wait.. just don’t want those tickets to run out.

So I am thinking to book it - just looking for the good time of the day

Thank you
