We just got in from a quick trip to Roatan last night. Weather was pretty good- a small front blew in one evening, but just caused lots of wind and blew out the next morning. It was in the 70's and the water was fairly clear for this time of year. We have always felt safe on Roatan, and if you are at CCV you are actually pretty cut off from the rest of the island anyway.
We spent a few days in Copan at the end of our November trip. It is worth
spending a day at least and if you have the time try to get to the bird park- it used to be on Roatan, but now they have acres developed into an award winning park. The Hedman Alas bus is very safe and comfortable-definetly the way to go. I believe the bus incident reported in the news was between Tegucigalpa and San Pedro Sula on one of the inexpensive "chicken" buses.
Use common sense in both places and you will be at least as safe as anywhere in America (probably safer). There are some good places to eat in town- Twisted Tanyas is very good (yes- Tanya of Twisted Toucan fame sold the bar on Roatan and opened up a place in Copan- very good food), and there is a little place called Nia Lolas- it has wonderful grilled kebobs and a waitress who carries everything on her head. Souveniers are much cheaper in Copan- there is a much larger assortment of Lenca pottery at about 1/4-1/2 the price as Roatan (I love this pottery- had to bring back some of the cute fish) and hamocks are about $12-15.
The ruins are a lot of walking and climbing so wear good walking shoes and bring water. The private tour guide (I think the guide costs an extra $30) is well worth it. When we were there the museum was closed due to roof problems, and it sounded like it might be a while before it would be open again.
Make sure you take the little taxis out to the ruins- they only cost about 50 cents and will save you a long walk on a busy road- also they are kind of fun.
I'm sure you will have a good time!
