There is almost always availability at Landmark and Wyndham PC for off season, but rarelly is there a summer June or July week, and when a 2 bed unit is available it will cost you about 45 TPU's. Typically you can exchange for a 2 bed unit off season at the new Wyndham a little cheaper than the cost at landmark. Both are Oceanfront resorts and I love both of them.
The Landmark is older and not nearly as plush as the Wyndham. If you require Wyndham amenities you will be diasppointed in Landmark. Landmark has spectacular views and a less crowded beach than the Wyndham has. The pool at the Landmark is indoors which I like to get out of the sun. The units at Landmark have washer/dryer, full kitchen, and every unit has a private oceanfront balcony except the one bed units which have an oceanfront ground floor patio. My friend owns Marriott legends edge in PC. He scheduled a trip the same week as we were down one year and he came to visit me at Landmark. He couldn't get over the view from the deck and den. He said his Marriott unit is much more plush, but that he has a view of the golf course and that he is labout a 20 minute drive to a beach. He said he would rather stay at Landmark. I helped him find an e-bay week to buy. He currently exchanges his Legend's Edge for something else each year through II and he stays a week each year in his Landmark unit. I personally would rather have an older ocean front unit than a brand new 4 seasons unit near the beach, and after visiting Landmark my marriott owning friend felt the same way.
The Wyndham PC is only about 5 years old. It is very new, very nice, and oceanfront. It has a Starbucks, a bar, and 2 pools. I don't like that the parking is across the busy street from the resort making you take an elevator in the parking garage up to a skywalk across the street, then an escalator down to ground level, and then an elevator up to your room. Also I am not sure all units have washer/dryers. Other than that I love this resort. It is the nicest Oceanfront resort onnthe Florida panhandle. If you exchange for this you get the best of both worlds, a very nice almost new room, and an unbeatable oceanfront view.
Also there is the Escapes to Tropical breeze in PC which is oceanfront. It is also about 5 years old, very nice, but hard to get because there are only about 35 units at the resort. The pool is not crowded, the beach is not crowded, and you can walk to a couple of restaurants without having to drive anywhere.
I stay in at least one of these 3 resorts every year. Sometimes I visit 2 or more of these resorts in a year depending on what I find for exchange and when I can get off of work. Other than those 3 resorts I do not stay in Panama City beach. I own at Landmark but usually rent my week out for profit (fixed july week) and exchange for off season week when the TPU value is not so high. (May, Sept). I do not own at Wyndham but have stayed there 3 times in the last 3 years. I own at Escapes but usually rent out my fixed one bed room memorial day week and can never find a week for exchange here that i want. All 3 resorts are on the west end AWAY from the teenage crowds. Do not stay near thomas Drive unless you are very young or young at heart.
Feel free to ask any questions. I love the PC beach area, many of it's restaurants, and i love the Wyndham PC, the Landmark, and escapes to Tropical Breeze.
