I am an owner @ ABV and here's my low-down. The units are somewhat older, but refurbished every few years. The decor is a bit outdated--just surf the web for "festiva atlantic beach" and you will get the website with photos. Some of the walls in the wooden buildings are a bit thin--but I am a light sleeper and it never bothered me. The area does not have much nightlife and is sort of boring for young adults and teens. That's the negative.
The + is the beach---wide and fabulous. ABV has a boardwalk-catwalk over to the beach and it's only ABV and a few houses--no public access--no crowds, no riff-raff. The beach slopes gently out vs. OBX bigger drop off. So, it is perfect for kids. The beach also gets some good wave action---simliar to OBX and much more so than MB or HHI. The property is well maintained with 2 very nice outdoor pools and also an indoor pool. Many who stay in the summer have owned for a long time and use their weeks every year.
If you enjoy an old-fashioned beach type vacation without a lot of frills, this is the place. I am a bit of a DVC, Marriott, HGVC snob these days, and it's certainly not to those standards, but if you want a fun, clean, spacious TS with great family atmosphere, fab beach and good pools, ABV fits the bill.
ABV is a silver crown in RCI and 5* in II. Elaine
