Kimberly - It's just me for the 5K; DD will stay back. Taxis are never a problem and vary in size from sedan to minivan. We just need to call down ahead of time, sometimes the night before and they'll be waiting. We did it last year from BWI to Minnie 15K start and DH did this from AKL for an early morning MK train tour. PM me your email if you want.
I will send my email to you. I will talk to dh tonight, and see what he wants to do also. Who do you call...the actual taxi service or can lobby guest services reserve one?
