Hi rj rub, welcome to Cruise-Chat. Did you check out the Roll Call Section a little further down the main page? If not, check it out to see if your sailing is there and if there are people going. If there are, you can PM them. To add your cruise to this list, if it's not there, simply click on the Reply button.
We'd like to not turn this board into advertising for mates/excursions, mainly due to the liability for the owners of this board. However, we do understand that sharing a tour is less expensive. We'd simply like you to do it via private messages.
Hope someone will reply to you. If not, I'm sure you'll meet people on board who might like to share in your excursion. Best wishes!
