I think it depends how many of you will be in the room and how long you will be staying. I have stayed at seralago but not the other one...its not a terrible hotel for the price.
I think possibly a better choice would be to get a hotel from hotwire. I just got the quality sweets around the time your going for 55 a night...so far I haven't had a bad experience from buying through them. It is a risk though being no refunds and all.
You can usually guess the hotel from checking betterbidding.com...besides one stay at seralago and one in a condo all my offsite experiences has been through them and so far I havent been disappointed. Knock on wood.
Good luck...I had the kids suite and nephew liked the bunk beds but overall it was a standard hotel.
