January 27th!!!! I would be super excited and nervous too. Just remember what every Dreams Cancun bride says - your wedding will be perfect and don't stress because everything will get taken care of at your pre-wedding meeting.
As for the fire drummer show, $1250 certainly seems a bit steep. Although every price I have seen for any fire performance on this forum has seemed outrageous. I hope you are able to work it out with her because that would be amazing for your guests and the pictures would be phenomenal.
