I'm planning an extended trip (weekend to weekend) later this year, likely staying at Paris. It may work out cheapest to try to use offers and get comped at the beginning and end of the trip (weekends) and then pay for the middle (mid-week) nights rather than make 1 consecutive reservation which would at least have me paying for weekend nights at the end. I know they can then combine the reservations so at least I don't have to change rooms. How many nights in between comps do you have to have? I seem to recall it's either 2 or 3 nights. For example, if I used an offer to get comped on Saturday and Sunday nights, would I next be able to use an offer and get comped on Wednesday night or Thursday night? Thanks!
