Hey just wanted to mention that Belize is considered "Malarial" by the Red Cross. So if you visit, you will need to wait 12 months from your departure date before you can donate blood again.
No big deal really, just adding in what I found out last week. So check it out if you are a giver.
For instance, if you visit Cancun proper, only, you are fine. If however you visit a ruin, Tulum, Chitzen Itza, etc., you may not give for 12 months. I would think this should include the ruin in Cancun itself "Del Ray". It's a tiny ruin south of town, but loaded with critters at it's North end.
I know I've diverged, but they don't call me "Master of all things arcane" for nothing.
