Hi, have you heard of Dalraddy Holiday park? Its just outside of Aviemore heading out towards Alvie, a couple of miles drive and there is also now a direct cycle way from the front end of the campsite into the edge of Aviemore so you don't always need car (some short, sharp hills though so not ideal for cycling for a weekly shop!)
I've stayed there in a privately owned chalet but they're all similar in shape and set up I believe, different sizes which can sleep up to six I think. Some folk live there permanently. No idea if pets are allowed but the setting is lovely and you're not 'on top' of the neighbours even though its on a site. I would make sure you ask specifially about chalets 'round the back of the site with view out to the hills' they have the nicest setting, not sure how many others there are on the site in total but would suspect some are shaded in trees etc... If you're after good wi-fi/ signal etc then I wouldn't expect too much- my vodafone network is useless.
