Limousine Service serving DLR?

[MPLsDad]

Can anyone recommend a reliable limo service they have used while visiting DLR. We're going to need a towncar to take us to San Pedro, but I hesitate to book without a recommendation since we're out-of-towners! Thanks in advance. P.S. I can't wait to get back from DLR (not that I'm rushing things) so I can share with all of you since you've been so generous with me!
