Go to Punta Bonrinquen very consistent, clean and fun.
Check the thumbnail below a nice shot of Wildo from the air. Many areas to surf and way more consistent on the north sure then in Rincon. Stay at La Cima inexpensive and near all the breaks.
I took my family down to stay in Rincon Beach Resort and it was nice. Not super delux, but nice. Did the caves thing... pretty cool. You can also drive to El Yunque and check that place out... really cool too. The surf will not disappoint, and when it's flat, you gotta take her out to Tres to snorkel.
Might not be too crowded... October is not peak tourist season. Even when it is crowded, Marias can get pretty spread out, with several lineups from the point through Marias, down to Dogman's. Be careful on the inside and the shallow spots down the line toward "stacks" or whatever they call it, where pipes stick up out of the water.
You'll have fun. I am jealous.
http://maryleesbythesea.com/, that you could stay at and explore a couple days to Ponce to the East and Cabo Rojo/Boqueron & Puerto Real (fishing village area with some real good no-name restaurants) to the west.
For October surfing and romance you might be better off at one of the villas/hotels just east of Jobos (there is also a nice villa west of Jobos) -- maybe a little more romantic than living amongst a swarm of gringos in Little America (Puntas). Jobos will probably be a nice beach for you to surf at and for the new wife to hang out at as there is some nice sandy areas for swimming in calm waters inside the cove.
BTW, Puerto Rico isn't really "out of the country" especially if you have been to Little Havana in Tampa or S. FL in general... just different than Iowa or Indiana.
Another suggestion while out on the Island (and away from San Juan which is a smart move). Book a villa or parador down around Humacao or up in the hills around El Yunque or near Fajardo/old Roosevelt Roads Navy Base. You can easily spend a day in El Yunque and also a half day skin diving in the Fajardo islands area. Get a copy of Que Pasa, the tourist guide, and a good travel guide to figure out the details. From the E/SE end you can drive to Guanica, stopping in Ponce along the way.
I don't think you will want to paddle out at Inches on the SE coast near Patillas. A very nice left on easterly trades or storm swell. Shallow and full of fire coral. If you get burned by the fire coral then you can seak out some Santeria in the nearby town of Guayama, the center of Santeria in PR :)
Have fun in "another country" and try not to wear it from a sponger or on the reef. Oh, and watch yer cornhole bub.
