limo bus or coach bus

I am looking for a coach bus or a limo bus to take a wedding party of 26 to my wedding. The bus will start the day in bayside and end in Northport.

I am also possibly looking for a coach bus that cannot only take the wedding party and family to and from all sites and maybe make two or three stops at the end of the night.
I have heard that I can rent a bus for the day and it will make may different stops when ever we want the to.

PLease help.

The wedding date is July 20, 2008

THanks Heather
