Write me an email to a professor respectfully declining their request for my attendance at a conference

Hi Professor,

It is so great to hear from you. 

I am so glad you thought of me to attend this conference. Unfortunately, I have a tentative vacation planned that week but please do keep me in mind for future opportunities. 

Thank you,
