I echo what Tom said: beautiful property!
Since 2009 I've been helping a couple of boutique resorts in Turks and Caicos with their marketing and booking strategies. This isn't the place for a soup-to-nuts explanation, so I'll just share one big break-through for them: TripAdvisor reviews.
Your property is probably already on TripAdvisor, but do you have a strategy in place to help you get positive feedback on a consistent basis?
Most managers and property owners have a love-hate relationship with TA, and I don't blame them. But positive reviews drive rankings; and rankings, visibility; and visibility, bookings.
We kept it really simple: At checkout, give guests a branded Thank You card printed on cotton or linen paper with step-by-step instructions for setting up a TripAdvisor account and leaving a review. Then send a follow-up email the next week saying that you'd love to hear more about their experience on TripAdvisor. Include the instructions and TripAdvisor link in the email as well.
If someone does leave a negative review, simply apologize, share your perspective, and ask them to give you another chance to impress them. Then offer them a free stay. That will raise eyebrows and take all of the risk out of booking with you, and can help you turn critics into your most vocal advocates.
This one little strategy worked like a charm for us, and because we were able to achieve such high rankings so consistently, the properties started winning Best of TripAdvisor awards, which compounded the effects!
I hope you'll give this little strategy a try. Let me know how it works for you.
