Recently we travelled from Ontario Canada to New Orleans and back. After New Orleans we stayed one night at the Balmoral Inn in Biloxi Mississippi. I researched this hotel and watched their website video prior to booking. It looked so 1950's, clean, simple and homey. Unfortunately upon check in I quickly realized that the promo video on the website was probably shot in the actual 1950's!! In actuality the place was run down, in need of repair with broken pool furniture, ripped lounge chairs and the dog show was in town!! So we had dog kennels set up right out front of our door and little "bags of dog poo" had been gathered off the lawn but left laying around everywhere. I had booked this hotel 4 months in advance and found it reall offputting when the proprietor of the property casually told us that "his dog show people come first" and that he "had bumped us 7 times from room to room to room to accomodate them.
Now, after saying all this, we had been on the go for a week and we spend the afternoon around the pool which was very clean and enjoyable.
The bottom line here is don't be fooled by the video you will watch for this property. It is NOT a reflection of what you will experience. The beach is within walking distance and the town of Biloxi is very interesting.
Don't miss the Frienship tree at the University of MIssissippi at Gulfport - it is truly amazing.
In a nutshell, the Balmoral will certainly suit your needs and kids will have fun in the pool. It is laid back and if the owner would do a little maintenance it could actually be as cute as the video portrays it to be.
