New logo wanted for National Convention

The Love Boat

In-home party company for women, similar to Mary Kay or Pampered Chef

We are looking for a logo to use for our annual (2012) National Convention. The theme is 'The Love Boat'. We will use this lock up for brochures, web banners, flyers, letterhead, onsite signage, and slide show presentations. We are looking for creativity and fun. The colors of our company are pink and black, however don't feel like you have to stick with those colors. Ocean blues and aqua could work too? Attached you will find:
1) Our company logo is the heart attached.
2) Concept for the Lock Up for the Love Boat Theme and how we would use it on a web banner
3) Concept for the Lock Up for the Love Boat Theme and how we would use it on an flyer
4) Last Year's National Convention Sparkles & Spurs Theme Lock Up that was used on all collateral.

We were thinking of incorporating a lifesaver type thing but are open to any and all ideas!
