Casa Del Mar is a low-rise hotel maybe 3 stories that has been there forever. It has always been a favorite for the "no frills" diver crowd. Nothing fancy, just a good, clean, well operated hotel catering mostly to divers. It used to be La Ceiba's sister hotel before El Cid bought La Ceiba. It is located across the street from the beach just north of the international pier in the same area as La Ceiba and Park Royale (or what ever they are calling that place this week).
It's only about 2 miles or so from town, we've walked to town from La Ceiba many times so it's not that far. the cab fare is around $4. another plus is Ernesto's is just across the street, a great place to eat for any meal.
I'd re-think using Del Mar Aquatics, from what I've heard from other divers and locals they have become a cattle call dive op for the cruise ships with over crowded boats and below average service, (this is just what i've heard so any Del Mar fans don't yell at me!)
Dive with Martin is a great op with a shop in the international pier's shopping center just a 5 minute walk away. they will pick you up at what every pier the hotel is using, but you'll have to go to the shop to sign-in and pay and if you want to do a night dive they want you to leave from their peir at the dive shop.
He has some the best prices on the island, with a free night dive and/or video and a 10% discount with a certain amout of dives booked. one thing, cash only. check his website for details

my wife and I dove with them in Sept. and had a great time. we dove 6 days and got all the specials listed above.
Another good dive op is Blue XT Sea, Christi has a very good rep. with divers and local merchants alike.

a third choice is Bottom Time Divers, Raul worked for another dive op for years before starting his own, he's a great DM and great guy.

p.s. not to beat a dead horse, but showering with friends ain't always a bad thing!!
