At the travel agency

I´ve never gone at (to) the Travel Agency to organise (organize)a trip. I´ve always organised (organized)my own trip, because I like preparing my itinerary and take a looking in (at) the internet about the economical prices, adventages (advantages), and the best places to visit,(.) The accommodation... I think, if you have sufficient time (it is) is better organise ( to organize) the trip by (on) your own, but if you go to travel without time (but if you do not have the time) is (it is)better to go to a travel agency because they can advise and recommend you the best places to visit, get accommodation, and the transportation. Although, the trip will be more expensive, but more (very)secure.
 
It was a very nice paragraph, but these are the corrections for the entry.
