Janelle from Island Bliss Weddings? I have booked her and she is absolutely fabulous. She is a great communicator, always replying to me within 24 hours (even before I booked her and had a million questions). Her attention to detail and pleasant demeanor make me feel as though I am her only bride, even though I know she probably has hundreds of bookings right now! You can't beat her prices either.
I would email Janelle as well as DestinationWeddings.com and compare their prices and responsiveness, and see who you connect with more, even if it is only via email.
You will be pleased you chose St. Thomas (if you end up choosing it 100%). I've been there twice and wouldn't have picked anywhere else. It is stunning, fabulous weather, great locals, and true paradise. We love the Virgin Islands so much that after our wedding cruise ends we will be heading back there for our honeymoon (splitting our time in between St Thomas, St John & Tortola -> another place that is heaven on earth). Your guests will be thankful you chose St Thomas too!
