I have recently posted a review on tripadvisor for the Comfort Inn LBV so take a look at that.
I would avoid looking too closely at reviews though. With the greatest of respect USA guests tend to expect a lot more from their hotels than say guests from the UK and this is often reflected in the reviews posted.
We stayed in November and I thought it was great. Price was $39 a night + tax which is dirt cheap. We had stayed at various Comfort Inn's across USA on that trip and we always found them to be very clean, have good furnishings, and very comfortable beds.
The Comfort at LBV didn't disappoint. Location is great, just 5mins drive from Downtown Disney but also in an area with some great restaurants....many within walking distance. Chicago Pizzeria Uno at the Crossroads is very nice.
The only downside I could find with the hotel is the breakfast. They offer a free continental option alongside a buffet which has to be paid for. The continental was ok but so many people were using this option that it was always so busy to get at the toasters etc. We didn't pay extra for the buffet option so can't comment on that.
I think you will be fine...
