Landscaping with Pavers and Stones .....?

Stones do hold heat pretty well. If the paving stones are exposed to the sun then yes they will heat up and hold the heat.

As Chris suggested go for a paving stone that is light in color as this won't absorb as much heat as dark colors.

If you need to know how to lay paving stones then take a look at this guide - http://www.hometipster.com/DIY/how_to_lay_paving_s...

Hope this helps

They could have an impact so consider light colored stones. But also consider where the stones are located. If they are not too close to the house then don't worry about radiated heat. Also, think about how much sun they get if any and consider what time of day they receive the sun. Late afternoon, evening or morning sun might not have much affect. Direct sun in the afternoon will. Lastly think about where the sun will hit them in relation to the time of year. Direct summer sun if not shaded by trees will have an impact but Winter sun when the trees have no leaves might be a good idea.

Yes and sort of no.

If lighter colored pavers are used than the heat absorption is minimal, like the difference between walking bare-foot on concrete versus tarmac.
