well all i can tell you is what we did, first find a great TA (travel agent) then if its a fast engagement...either STD (save the dates) or right to invitations..if your doing them yourself Michaels has a great selection of DIY..then after i sent out the invites its right to your decorations, travel stuff OOT (out of town bags) for ppl who are going..a ton of templates..which u can find on here lol talk to your resort which is where your TA will come in handy!!!!! find out reception info private or semi private, menu choices. pick your wedding package which will be on most resort websites. And well there is more lmao but that will get you started..BUT FIND A GREAT TA SO LESS STRESSFUL!!!!!!!!!!!! if you need help all the brides are info full.
Good luck, if you need anything just yell lol
