What can you do besides a limo - Looking for creative solutions

I'm having about 3 hours between the end of the cermony and the reception for the pictures - my photographers have been telling me to be prepared to pay overtime for the extra time needed. Is there anything different that could be done where I could avoid this.

I thought of renting a few classic cars for the day or something - but that idea may not work and I may just have to suck it up and pay the extra for the limo
