We just returned from our wedding at Dreams Tulum. We had a 2 o'clock wedding and it was HOT! If I could change anything about that day it would have been the time. We tried to take group pictures as quick as possible after the ceremony but people we leaving to get drinks, looking for shade. It became very frustrating. Another suggestion would be to have the wedding at 2 oclock the ceremony itself was not that long. Join everyone for the cocktails right after and get pictures done later in the day when its not so hot!
