hi! we are going to costa rica again for our 4th time in april! the first time we went we stayed up in Liberia at allegro papagayo. we went on a zipline excursion & it was amazing! we have friends coming with us this time that really want to try it! if I remember they were the longest & fastest. does anyone have any info on them? we are not staying in that area this time but will make a trip there to do them, we have a rental car. also we are staying in manuel Antonio, quepos area if anyone has any recomedations for us it is greatly appreciated! thanx!
