Luchdiamond: you can go with the complimentary package and then add things that you want a la carte. Read the review by CutieRosie. It's very detailed. She did the complimentary package and had a huppa on the beach in addition to lots of other things. She also posted some great pics.
Jodimichelle: my FI works for Continental. The summer airfare price wars usually start in May. Also try www.airfarewatchdog.com; this is a cool site that will send you email alerts with airfares. You can chose how often you want to receive them and you specify if you'd like alerts from a certain city, to a certain city, or city-to-city. Additionally, let your guest who don't use this site know that the best time to shop plane tickets is Mondays, Tuesdays, and Wednesdays.
