You can always simply book at the prevailing amount and never check again, if the amount being asked is OK by you. I constantly recheck my car rentals up until the time I cant change it any longer. On recent trip to MIA I checked upon arrival and it was $20 less so I CXed the old and rebooked. I didnt have to recheck and many times it doesnt result in asavings
