The 2009 Sisters at Sea trips are the Caribbean FunRaiser cruise and the Rome To Barcelona Ultimate Escape. The Sisters at Play are the Columbus Isle Resort and the Ixtapa Resort.
If you click on the "Travel" heading, you can read about all of these great trips and choose which one you like. Then, you call into Olivia and book it, telling them you are with the Sisters program.
You may get an extra discount for being in the group, the representative will give you the best deal. If the trip is already discounted, you won't get both discounts but you will get the best.
You should book your trip as soon as possible because you can set up a payment plan once you put down your deposit. You can even get the Olivia credit card if you choose. That way you get lots of discounts and travel points.
I hope this helps. If you have any other questions, just let me know.
