Hello wedding planners! This was a sudden change for everyone down here and there is still some confusion with some, don't be too hard on your coordinators.
This is a good thing, longer days, more sunlight! Basically we'll be on daylight savings all year to have some wonderful sun time. You may consider moving your times to get those sunset pics or avoid the heat, but do remember that if your date is during the "regular" daylight savings time, you won't be affected anyway. Sunset pictures are a bit more complicated here as we are on the east coast, but definitely possible to do! Your photographer should know the best time/place for that perfect photo. In Cancun, the lagoon offers INCREDIBLE sunsets!
Happy planning my amigas!
