Peru in March/April

I will be heading back down to Peru at the end of March through the first couple weeks of April to be there for Daniela's birthday. I am excited about the prospect but right now I only have the details about getting there and home. We haven't yet decided on the specifics of what we are going to do while I am down there. I am again flying AA. They just seem to have the best flights for what I have been trying to do recently.  I am sure I will spend some time in Lima and meet her family at the very least.  For that reason I am trying to use Rosetta Stone to learn Spanish. I am not sure how far along I'll be by April. I hope it is good enough.
