Hi Lori,
We will also be at the Now Jade from May 3-10 and our wedding is on May 7. Don't worry, you're not the only one, we are leaving in less than 5 days and are not fully ready yet. Still working on our playlist, as I write this post.
We have 36 guests, majority of our group is in mid-30's too. I had the same concern and really hope it will be a bit lively when we are there. Maybe with our 2 groups, we will be able to put some ambiance at the sports bar/disco of the hotel
Have a nice trip! What day is your wedding again? We are leaving on Saturday!
