Mexico with Mike

I am going to Mexico with Mike. He and his whole sales team won an all expense paid trip to Playacar Riu Resort in Playa Del Carmen Mexico, from the company he works for. He invited me to go with him to celebrate his 50th. I am going from Feb 6-11. It was a hard decision b/c I feel really guilty and I am a little nervous about leaving the kids after all the ordeal. Cristy is coming down from DC for Tues-Thurs and then Jason is taking the rest of the time off work and keeping them. Jason says I should still go, but I am really struggling with this decision. Jason thinks the trip will help me rejuvenate....but I am really nervous about leaving them....I have never been away from them.
