I am travelling with my husband and our 3 children ages 16,14 &amp; 9. We are visiting Brazil during the 2 last weeks of January. My sister is also travelling with us, together with her husband and 2 children ages 15 &amp; 10. In total our party is 4 adults and 5 children. Would it be possible to check in on Saturday 15th of January ? What package can you offer us ? Thank you
