Is there a "welcome pack" tryout ?

Hey,
I am thinking of returning to World of Warcraft after quite a long pause and I wanted to ask if there is an option to try the game for a restricted amount of time (like a "7 day tryout" period..)
My highest level character was 100, so level 20 starter edition is not what I am having in mind

Thank you!

I didn't find the right solution from the Internet.
