Rest is defined as sleep or repose, but under the Split duty provisions it is all time that is NOT pre/post flight duties or traveling. So walk in to walk out of the hotel.
You have quoted the words, and the intent of OMPA correctly, and it is certainly the company's ideal interpretation that "because we have told you rest does not include traveling time, or post-flight duties, therefore everything else IS rest".
I put it to you that your 3 hours of rest must, in addition to OMPA, meet a reasonable person's definition of rest, ie repose or sleep.
Standing at a crowded, noisy, smokey, check-in desk for 20 minutes, listening to doof-doof music is not rest (and I therefore delayed our pick-up accordingly). We were in the hotel, but we were not resting.
