Oh, Karla, they will have a wonderful time!
What a wonderful gift to your children!
I can relate, though..... The 2 years 3 months my youngest served in the Peace Corp in Nicaragua was worrisome to say the least....... She was sick a lot of the time and the living conditions weren't the greatest. On a positive note, her Nica neighbors were like family to her and made sure she was okay on a daily basis. I am still thanking them....
