Looks Good to me, I've been busy planing my trip too and here are some things I found

1. Your LAX-DFW-SJU can be done with one flight number therefore you will only use one of your NA flights (stops in MIA), a better one is from LAX-SXM, stops in MIA & SJU (Thanks Bers~!)

2. I'm not sure what (o) means (I think a place you want to stop and check out, I didn't think it would be a land sector because of the LHR-DXB(O)-LHR seems kinda far)

3. I wanted to go to The Galapagos also and did some looking into it and found that it costs US330 to fly round trip to the islands from UIO and another 100 bucks to enter the park above the cost of Cruses, Tours, Food and such, I decided not to go because it's too much $$ and I get sea sick hehehe for my SA stops I picked IPC, CCS, RIO. Oh yeah they had some cheap 'Learn Spanish' classes in the Galapagos, tell me if you want links (I decided to spend 2 MO's in Costa Rica learning it before I go to SA)

hope this helps, but remember I'm new to OW too (look for my Itin posted in a little while)
