Are those the only dives
both of you are planning to do? If so, I probably wouldn't stay at any of the AI Dive resorts as they're all fairly isolated - some more than others.
If you're planning on daily diving, you can also buy a dive/non-dive package for each of you from a resort. Or ala-carte from any number of shops in the West End/West Bay and find your own accommodations. Some resorts in West Bay (nicest beach) also have dive operators on-site. Dives are typically $35 or 10/$300 - some include gear - others it's $5-10 more.
One option is have your partner do the Discover Dive program. On Roatan (depending on where) it's minimal classroom, maybe some quick pool skills (if the resort has one - Cocoview/Reef House don't) followed by a shallow beach dive then the Discover Dive - either from shore or boat. Typically those are done in the afternoon.
Some of the operators - Cocoview, Anthony's Key, Coconut Tree Divers in the West End, also offer an additional dive for $50 afterward. Since some of the Discovery Divers have to head back for their cruise ship at that time, it's possible it could be your partner, their Instructor and you. I doubt any of them would have a problem with you tagging along if you pay also. I honestly can't see any reason why they wouldn't even do a dive the next day for $50 - their schedule permitting. Things are pretty casual on Roatan and most things I've wanted out of the ordinary just cost a little extra. Or ask your shop for a Guide whose also an Instructor and pay them directly just to take you both out.
You could also boat dive while your partner is in class - the reef on the north side is about 5-10mins. out in most cases and they need the boat back by noon anyway for your partner's dive. In the West End there's even time for lunch nearby.
You should do some boat dives, the reef in most areas is pretty shallow and in summer it's pretty calm. Since many shops also train DM's they may have more than one shadowing your group. So if you want to stay shallower there's someone who can stay with you. Just let them know when you sign up. I shoot video and like the light at 40-60' so several dives I had my own DM trainee follow me. I didn't need them but the shop liability said I had to have one - I didn't pay anything for it.
If you could define your expectations/ requirements better someone here might be able to make a better suggestion.
You can't bring too much bug spray either...
