Yes like I said above:
1) "Claims made against only a portion of your entire scheduled stay will not be honored":
a) Do not pertains to you since you have not booked a 2 nights stay and claiming against 1 of the nights
2) "Multiple claims for a stay consisting of two or more nights in the same week at the same Marriott hotel or Marriott hotels in the same geographic location (e.g. city) may be treated as one claim for one stay, even if booked through more than one reservation.":
This is only interesting in the context of awarding points, otherwise they need to advise you on how to book two hotels (with not adjacent nights) in the same reservation on marriott.com if they cannot do this you have to have two or more reservations that you claim against individually and they are treated as the same stay for points claims.The T&C explicitly mention that you can have two or more reservations which by definition are claimed against individually.
Needless to say it is impossible to have a 2 night stay (not not necessary adjacent nights since the T&C mention one week) at two different hotels with the same reservation number so what their reasoning results in is an absurd outcome, i.e. their interpretation of the rule implies that such reservations must be possible to make which they are not so that makes their interpretation mashed snow
This rule only have a meaning for points awarding since you can stop abuse of the 5K awards when someone try to do hotel hopping with LNF.
