Yes, I don't like the smoke either, particularly when I am singing. The joy of the pewter room in the Fleece Inn, which is a National Trust property and which goes back to the 15th century at least, is that it is a non smoking room!
There is plenty to see in terms of Shakespeare, in addition to the town itself, there is the Theatre and the Shakespeare Trust properties. there are lots of websites to lokk at, including: stratford-upon-avon.co.uk, stratford.co.uk and rsc.org.uk.
Anyway, speak to you further when you have sorted your programme!
