As we get closer and closer (6 weeks on Tuesday!) it is the smaller details that are starting to drive us mad

There is only us 2 and my fiancé's parents with us on the day. We have spoken to our photographer about timings and where we want to go for photos - mainly the Bellagio, Cosmo, Caesars and the sign. We started to look at limos for transport and also to get me to Caesars for the ceremony - we are staying at the Cosmo. I was going to walk but it's longer then I remembered after checking Google maps.
As our hotel photos are all quite central I am wondering whether to hire a limo to pick me up from Cosmo and take me to Caesars - wait until the ceremony is over and then take us to the sign and then drop us back to start our main hotels tour?
What did you do/are you planning to do if you were staying in a different hotel to where you get married? Did you use a limo just to get around the more central hotels for photos?
I don't know whether to just hop in a cab or Uber to get to the ceremony and sign but I am worried we would be waiting for a while to get one for the two of us and our photographer!
Sorry for rambling, I just wanted to get this all down - thanks all
