Unless you have a history of living here on back-2-back visa exempt or tourist visa entries
@Diane *********
you should no problem comin' back to thailand on a 30 day visa exempt entry after you had a 60 day tourist visa entry with a 30 day extension.
in case you're asked be prepared with proof of funds (20K baht or the equivalent in CASH), proof of onward travel and proof of lodging and you should be fine.
