Here is where we stay in April. I figure anywhere from 1-5 of these change on a monthly basis.

abe, ags, alb, atw, aus, avl, avp, bhm, bis, bmi, bna, bos, buf, bwi, cae, cho, chs, cle, clt, cmh, crw, dal, dca, den, dfw, dsm, dtw, ecp, evv, ewr, far, fay, fsd, geg, gnv, grb, grr, gso, gsp, hou, hsv, iad, iah, ict, ilm, jan, jfk, las, lax, lex, lft, lga, lit, mci, mdt, mdw, mem, mke, mob, msn, msp, msy, myr, oak, okc, ord, pbi, pdx, phf, phl, phx, pit, psc, pmw, rno, san, sav, sdf, sea, sfo, sgf, sjc, slc, stl, tlh, tpa, tri, tul, tvc, vps, yyz

Pretty good list. Too much effort to tell you how many times we stay at each one . I assure you those cool places like PDX, LAS, and SFO are places you won't see much if at all, while garden spots like EVV, LFT, JAN, and FAY will have lots appearances in the bid package.
