Hi, we're going there too and will be arriving a about a week after you.
We have seen the mixed reviews but are not too concerned as more than 50% have been good or not too bad reviews and you can't please everyone all the time.
The only thing that concerns us out of the not so good comments is the noise from the Interstate. We didn't realise it was so close when we booked - we didn't even know what side of I-Drive it was.
I am going with an open mind in the knowledge that it's a Virgin Flagship and, if I am not happy then I will certain complain and push for a room move.
Perhaps we will see you there!
