Do any of you use The Nest website? They have all sorts of things on there. It's mostly articles and forums geared toward newlyweds, with topics like home decor, fitness, money, travel, crafting, food, fashion, etc... They send out newsletters too and I recently got one featuring party ideas for a fuss-free fiesta. Here's the party plan.
Send a bold invite to get your guests in a fiesta mood. They suggest an online invite to keep it easy, but if you're a paper freak then go for a great printed invitation (below invite by Boatman Geller).
