Hi Chibride (I can't see your profile to know your name!),
That's why I chose the Del Mar as well, we're hoping that people will be able to afford it and make an awesome trip out of it! Also, the resort has a lot more greenery than the other Iberostar resorts right there. It gives it a very romantic feel, I think you'll love it!
I also sent our my save the dates and have gotten some responses but no one has booked yet (not even us!) We're going to book this week and I have a feeling that will create a domino effect! I agree with you that predicting how many people will come is the hardest part. I wish I just knew so I could start ordering stuff for out of town bags (OOT Bags) as that's the part I'm most excited about, I have so many ideas thanks to all the browsing I've done on here!
I ordered my dress but that won't be in until April or May so I'm sort of at a loss with what to plan next. I'm just daydreaming right now I guess. I think the next step is ordering invites!
Are you going with DJ Doremixx? What photographer are you using?
