I keep checking and re-booking almost daily with Dollar for February using a combination of corporate and promo codes. Rate has gone down $5-10 for the entire reservation from the prior day in some instances. Worth checking up until the very end. I believe I have shaved off an additional $30 just over the past 5 days. Not a ton of savings, but every little bit counts.
I am utilizing a combo
AAA code and the best promo code I can find.
I am booking a week long mid-size for under $160 including taxes and fees in case anyone needs a comparison.
