As someone who works in the hotel business I will offer my opinions/insight. Forst it really depends how booked it is - if it' pretty full capacity obviously it can be much harder to get the rooms exactly side by side , especially 3 rooms.
With that said however , it isn't impossible. I'm unsure what HoJo's guarantee room type policy if any is in place. It may be a request based upon availability so keep that in mind , or call the hotel directly to ask. At the hotel I work for , we always try to accommodate requests as best we can. Obviously there are only so many rooms/types available per day and the length of stay can affect the ability to grant said request as well. It never hurts to ask questions , just keep in mind that they want you to be happy but there are times that every request cannot be granted so keep an open mind too. Good luck though !
