Get over it about the "loyalty part". Can't believe after the past 2 years how badly Marriott behaved in treating its loyal customers anyone would still hold a hope to get some real caring / assistance, from Marriott.

It is too early to tell where the hurricane will land. Bad weather with lots of rain is expected no matter what because this has been the Norm this summer - we have heavy thunderstorms with rain every afternoon the past 7 weeks already. Sometimes the heavy rain hit in the morning, sometimes both the afternoon and evening are hit with heavy rains that typically dont last more than 30 min but the rain happens every day, much wetter Summer than usual.

Hurricane is now being talked as it may be a Cat 4, from earlier Cat 2 to 3 only.

When the airlines issue waivers, Marriott would issue waivers as well, like they have done so in the past in similar situation IIRC.

Besides, what do you expect when you pick the hurricane season to travel to Florida? pretty much like people pick the Winter time to travel to Northeast for a vacation - you knowingly take the weather risk, so just chalk it up to bad luck and hope for the best if hurricane does come, then you get the waiver.

EDIT
Glad to read OP is accommodated by the hotel, which probably has had the latest weather update that this could turn into a Cat 4 by Sunday.
