@@tygrrlily. Cassie asked me to answer this one...
When we arrived at the resort, we were planning to just use a playlist on our computer for both the cocktail hour and reception. We happened to see/hear the band when we attended the Chef's Dinner on Wednesday night and Cassie immediately knew she wanted them for our reception. I inquired with our on-site coordinator the next morning and she gave us further details.
The group is "Basic Band" (such a horrible name for a band) and included 5 members. They have a huge playlist of popular songs (we saw their ~200 song playlist during the karaoke night on Thursday) It was ~$900USD/hour, which included 45 minutes of playing time and a 15 minute break. That said, I don't know if they took a break or not, since we were down taking pictures for most of the cocktail hour.
We hadn't budgeted for a band at all, so it was quite a game-time splurge on our part. When we walked into the cocktail hour and they happened to be playing "Stand By Me" - one of Cassie's favorite childhood songs - we knew we made the right choice (plus, a lot of our guests commented on how great it was). It would have been amazing to have them for the entire reception...but at $4500 for the night, I would have had to get a 2nd job when we returned to the states!
Hope this helps.
