Limo help!!!

I have a question. We need to 'limos' for our wedding, a limo for his parents and a bus for the girls.
Since FH won the limo from Serenity, YAY!! should we even bother looking at other limo companies?
I also wanted to do a regular limo for the girls to the church and then the bus from there, but I'm afriad that something will be left behind.
I would keep the one we one for the church idea, but since we somehow ended up paying for FIL's limo (long story) I feel I should just deal with the bus to and from the church.
Opinions please!
