There appears to be some confusion about which suite JFK stayed in the night before his assassination, but the hotel was The Fort Worth Hilton.

"The night before his untimely death, JFK was in Houston. Thursday marks 56 years to the day that president Kennedy landed at Houston International Airport (now Hobby Airport).
From there, the presidential motorcade traveled up Broadway to the Gulf Freeway toward the Rice Hotel downtown.
Thousands would crowd Houston's streets to the see the president and first lady, Jacqueline Kennedy. After a short time in their room at the Rice Hotel, the president, first lady, Vice President Lyndon Johnson and his wife, Lady Bird Johnson dropped in on a LULAC function honoring State Director Joe Garza.
From there, they went to the Sam Houston Coliseum for a dinner honoring Houston Congressman Albert Thomas. After that, they went back to Houston International Airport and departed for Fort Worth."

I don't see credible sources for JFK staying at The Sandman Hotel, although the building has historic significance.
"If you’re looking for a unique hotel in Dallas Fort Worth, look no further! Our 245-room, heritage building on Houston Street is known as“The Waggoner Building” and was completed in 1920. It was originally built for William Thomas Waggoner, owner of the Waggoner Ranch, and is listed on the National Register of Historic Places.This will make it one of the most historic hotels in Dallas Fort Worth and we’ve honoured the building’s past by retaining many of the original features you will be able to observe and enjoy during your stay."
