Pre-cruise hotel question

If Regent's website lists one hotel under the Pre Cruise Hotel tab, is that guaranteed to be the hotel you're staying at?

For example, I see on the Maiden Voyage trip report thread happening now that the guests who had the Pre-cruise night in Monte Carlo were divided into 3 hotels: the Marriott, the Monte Carlo Bay, and another one.

However, on my upcoming cruise out of Monte Carlo, the only hotel listed on the website it the Monte Carlo Bay.

Is it possible we may be placed in a different hotel?

Does your itinerary in the 'My Account' section of the website not show at which hotel you are staying?

I think once they fill up one hotel with the block, they move to the next.
