I have full custody of my daughter. the divorce decree custody states that visitation to her father is every weekend.

If the divorce/custody order states every weekend, but you want to change it, then you would need to go to court to get the change approved. Otherwise, if you resist, and your ex wants to try and enforce the original order, you would likely end up in court anyway. Your daughter does not exactly have a "choice," but she is old enough to express her opinion and rationale (to explain it to the judge). Her opinion and concerns would be taken into account. If you have a lawyer whom you trust to help you with this matter, then you should call that attorney to discuss your next steps to get the matter settled. Things change with kids, parents move, financial situations change....this is not unusual to have to go back to court to get something modified. For general info on custody, see -- http://www.utcourts.gov/howto/divorce/custody.html (there is a part there discussing the modification of custody orders). My firm handles family law matters. If you need a referral, you are welcome to give me a call.
