Our TA has taken some of the weight and pressure off us. Since we are having the destination wedding, we wanted to make everything easier for all of our guests. Working with the travel agent has allowed them to make payments on their travel packages on their terms, negotiated the group contract to ensure that we get everything that we want as promised, and is just making life easier. My FI and I constantly discussed whether or not we needed one, but since our STDs went out two weeks ago; the TA has already proven to be beyond helpful. Hope this helps! Happy Planning!
