European TA?

Hi. I’m still new here but have learned so many great tips. I have a mother/daughter trip planned for April 2019, booked direct with Disney, before the latest ticket markup and with 25% off room rates.
I understand that it can be cost effective to book through a TA but I live in Denmark. Which TA should I be using? Is there one that covers all European countries or should I use a UK TA? Or just a US TA??
Thanks for your help!
