A city hotel with a changed listing name
Agoda’s current listing is named Palette Legacy Udon Thani, while its legacy page address still uses Ban Chiang Hotel. Keep that name history in mind when reading older reviews: an account headed Ban Chiang describes the earlier name and may not reflect the current operation.
The property is an Udon Thani city base, not a hotel in the Ban Chiang archaeological village. The shared words in the former hotel name do not establish proximity to the national museum. A trip to Ban Chiang or Phu Phrabat needs a separately checked road journey and return arrangement.

Published room categories are the firmer comparison
Current Agoda room data lists Deluxe Double and Deluxe Twin categories at 28 square metres and an Executive Suite at 56 square metres. The named Deluxe Double has a double bed and the twin has two singles; the suite provides a different amount of space rather than merely a higher-floor promise. Decide whether that extra area is useful before treating an old suite review as a guide to an ordinary Deluxe room.
The present listing name and room descriptions do not, by themselves, establish that every part of the building has been renovated. Ask about the exact allocated category and current bathroom or air-conditioning condition if those points determine your choice. No refurbishment completion date has been established here.

Older criticism cannot certify today’s condition
The detailed Agoda guest accounts available include a November 2022 Junior Suite stay disrupted by air-conditioning replacement work and complaints about pool-area wear. A July 2022 Deluxe guest was much more positive about staff. A June 2022 Junior Suite guest described an older-style room and pandemic-era limits but liked the courteous staff and substantial breakfast.
These are historical experiences. They do not prove current construction, current pool availability or the service offered by Palette Legacy. The sensible use of them is to formulate room-specific questions, not to present either the criticism or the praise as a fresh review of the rebranded operation.

Who should keep it on the comparison list
Someone wanting a conventional city hotel with a choice between a 28-square-metre room and a substantially larger suite can compare the current offer. Someone looking for accommodation at the archaeological site should search by the actual destination instead of the former name. A useful reservation here is one that resolves the present category, facilities and location; the old Ban Chiang reputation is neither a current guarantee nor evidence that the property is closed.
