Re: I admit to having a (not Honeywell) smart stat
Yes, coming back from holiday occasionally shows the limitations of mine, albeit they aren't that big a deal. I can only tell mine that I'm going away for several days and which day I return. Most of the time I arrive back in the afternoon which means that the morning heating is wasted. If I return on a week day (unusual but not unheard of) it can mean returning to a cool house.
Then again I don't go on vacation much in the colder months and in summer the heating (although I leave it on all year round) won't be doing anything anyway. So better control over how it should handle the resumption of normal programming would be nice but is far from essential.
My model (a Honeywell CM67) had an add on module that allowed for some kind of control by telephone. I opted for the Radio Controlled Clock module instead though as that seemed more useful.
