I have always suggested a private transfer over the included group transfer. Here is a review today
On Anne Adams recommendation, we used AGI tours at the start of the month. They were very responsive to emails and got us where we needed to go in good time. On arrival, our plane was over an hour late & then we waited 2 hours for our bags. They were still waiting for us. We were able to pay in cash too which was nice. They stopped at a gas station so we could grab drinks & snacks.. after our long day of travel that was much appreciated
