There is not. The hotels are around 15 minutes or so from the ceremony venue and only around 5-10 minutes from the reception venue so it will be relatively easy to use a rideshare company of your choice (Uber, Lyft, etc.)
Formal attire, but if you prefer black tie then go for it!
Kids are welcome for the ceremony and cocktail hour, to view the gallery and have small bites. Prior to cocktail hour ending, the kids will be going with a family member for the evening. Please let me know if you would like for your little one(s) to join Macai for the evening.
Yes, there is free parking at both locations.
