vmrun wait?

I want to have 1 of my VM's started before any other, but do not want to run 2 batch files.

I tried to find a "wait" command, or something like it in the documentation but did not see anything.

Here is my batch:

cd\

cd "path\to\vmrun"

vmrun start "path\to\Server1\.vmx"

sleep 300

vmrun start "path\to\Server2\.vmx"

vmrun start "path\to\Server3\.vmx"

Will this now start Server 1, wait 300 seconds, then continue to load the remaining VM's

Thanks.
