Hi am new to this.. I get married 20/4/2016 at the grand sirenis and basically nothing is clear so I am looking for some help.. When will I be asked by someone to choose colour schemes ect? Also when will I get a choice to upgrade and add extras to my package? has anyone got married here? There are me my partner our 2 children and around 15 guests. What restaurant is good? What can I do for a "reception" as we don't have enough guests for the palapa any advice would be appreciated TIA x
