I'm planning a trip to Charleston and want to check for any special offers or packages at The Dewberry Charleston. Please list each available offer, stating its name, the required length of stay, and its validity dates as presented on the website.
Navigate to 'thedewberrycharleston.com'. Click on the 'Offers' dropdown or link. For each listed offer, identify its name, required length of stay, and validity dates.
State the name of the first offer as 'Complimentary Fourth Night'. For 'Complimentary Fourth Night', state that it requires a 'three-night stay' and is 'valid through December 31, 2025'. State the name of the second offer as 'Unwind Midweek'. For 'Unwind Midweek', state that it requires a 'two-night or longer stay with arrivals Sunday through Thursday' and is 'valid through December 31, 2025'.
