I stayed at POR during Easter this year, and was amazed at how quiet the rooms were. The grounds are well manicured and the facilities were adequete. Had a great time. The boat (which is an exclusive to staying here or POFQ) to DTD can be romantic as well has the horse drawn carriage rides. The paths along the river are well lit should you engage in a nighttime stroll. I saw a few people swimming in the pool as late as 10:30 pm.
If you want a nice pool, maybe you should look into CS. Southwest architecture. I thought the POR pool was adequate, but nothing special. It does offer a lot of shade.
A lot of honeymooners want the feel of a tropical resort, and the CBR would be your choice. I haven't stayed there before, but I understand the landscaping is very tropical where POR is more "deep south"
You'll have a good time no matter where you stay.
