Any opinions, preferences, experiences anyone would share with us as to who is best to use to go to see the manatees, for snorkeling trips, and particularly to go to see Lamanai and to go kayaking (easy trips - we are seriously out of shape and younger in our minds than our bodies but we are gung ho!!) We are totally avid snorklers and love to go for hours and hours. Are there any spots we can go and stay for the day if we want and not be held to a tour boat schedule? Thanks again everyone!
