You can book through Olivia as a solo, or you might get lucky simply posting the request like you did. This will be my 3rd trip, it's been pretty consistent around 20% on all 3 of the trips I've been on. You're going to have an amazing time.
I'll know by the end of March but not likely sooner if my friend has to bail. At this moment it is 80% likely. I bought the early bird pricing on the superior room, basically the cheapest one. lol. Feel free to message me if you still need a room. I'm a non-smoker and would be open to sharing if you too are a non-smoker.
Cheers to a great time :)
