I stayed at the Boulders Resort for 4 days, and I enjoyed escaping to the El Pedregal for a few meals. It was an added benefit because we were able to charge it to our room.
There where a handful of stores, most of the store fronts where empty. This could have been because of the off season, not quite sure but it wasn't a whole lot of shopping to be done at El Pedregal.
We stopped in a quaint, and dainty store that had hats from long ago when ladies used to dress and go to church and wouldn't dare be seen without a hat as well as some one of a kind pieces. She had a great jewelry stand shaped as a high heel shoe that could hold rings. She also had some great shoes with simi-reasonable prices. My companion and I both remarked that we could just google the retailer/designer for the shoes and jewelry box and get them for signficantly cheaper. I googled later that evening and her items were only priced 25% more than amazon.com without factoring in shipping, so she really did have nice prices.
There was a holiday store selling everything Christmas, and a salon complete with a mini boutique.
We left on Sunday morning, and they were setting up for the evening of jazz. I would have definitely loved to stay because several people recommended it to us.
I enjoyed the design and the architecture, and we took several nice pictures of the grounds for our scrapbooks :)
