Doc said it all, but I will chime in! Do indeed go with Papa Hogs: they are a great bunch! La Ceiba is a reasonable place to stay--it has a nice little mini-village that will let you do some shopping AND a decent place to have an ice cream! You can even walk into town--if you do not mind a walk of ca 45 mins (I think that is how long it takes me???).
Time share hawkers are all around San Miguel and I have learned to ignore them. But Doc is right, they can be somewhat aggressive!
In future you might consider two other hotels that, as I remember, are in the same price league as La Cieba: Fiesta Americana--very far south of town, and Plaza Las Glorias--not too far from La Ceiba. My favorite is Fiesta, but as of late the taxi fare to town has risen to ca. $7.00 each way: some folks find this prohibitive.
Oh, yes, January is Spotted Eagle Ray time on Coz. If you ask, Papa Hogs will probably take you to the site(s) where they are most likely to show up; Del Mar Aquatics most likely will not!
Hope this helps,
