Here's a review from Trip Advisor on the Hotel Galvez:
They didn't tell us it was haunted
"Although the hotel is beautiful and the service was great (except in the restaurant) when we made our reservations for a pleasant long weekend with our young children we didn't know we were going to be staying in a haunted hotel.
I have never experienced a "ghost" before this, have never wanted to, and never wish to again, but unfortunately on our first night there that's exactly what happened to me. My husband was not there, I had driven up a day ahead of him since he had to work. After I put my 3 small children to bed and got our bags unpacked I turned out the light and got in bed, no reason to feel any alarm. Then suddenly the speaker button on the room phone turned on and a dial tone filled the room. I immediately felt afraid and turned on the light. After turning the speaker phone off and finally talking myself into turning the lights off again it happened all over again. It wasn't until I actually told "it" to stop and prayed aloud for God's help with the matter that I was finally able to turn off the lights with no hair-raising occurrences following.
The next morning I asked the front desk and they said many people have had similar experiences and it's to be expected in an old hotel. Well Not By Me! When we returned home I did an internet search and learned the wing we stayed in is on the Haunted Galveston tour and the room my sister in law stayed in beside me, room 505, is considered to be the "evil" room in the hotel according to numerous web sites (she did not have any experiences and ridiculed me until we got home and read all the info on the internet).
Unless you are seeking an experience beyond our world I would recommend a different hotel, or at least stay away from the fifth floor!"
