It always ALWAYS takes longer than what you think or what the contractors say. Once they have you over a barrel, there are delays (some of which they anticipate and some of which may be the "surprises" that "just happen". So don't believe the "few nights" that are suggested.
My son just went through this - his roommate's parents bought a condo and they have been doing renovation. Mind you, no one was living in the space, and it still was a job that wasn't finished on August 30th but on October 8th. My son is a project engineer for a construction company so he knows what happens with subcontractors, appliance/supply delivery, etc. The owner of the condo wanted him to be the general contractor, which he agreed to, but the son wanted to make his own decisions. So he hired someone and agreed to things he shouldn't have, and the various aspects weren't well coordinated (plumbing, electrical, drywall, etc.).
A lot of people set up a pseudo-kitchen in another room with crockpot, microwave and dorm fridge (or more the regular fridge into the dining room or den). And yes, you'll do dishes in the bathtub or just go for paper plates as environmentally unfriendly as that is. Even if they seal up your cupboards and china cabinet, you'll have dust in there. In the hall closet too - places where you don't even open the doors! So it's going to spread more than you think!
You could look into one of those extended stay places with a kitchen, which will have the bare bones of kitchen equipment. You could take some of your stuff over there too. Sometimes they have weekly deals especially when they have vacancies. And if you have AAA, look into discounts for members too. And check Priceline and Hotwire and similar services - most people think of them for vacation and not for something down the street, but why not? These extended-stay suites are not the sort of places that get overnight visitors so an empty room/suite isn't' going to get an unscheduled check-in like a regular hotel. So it may be cheaper for you than a "standard" hotel, and then you will not have the cost of meals out. Your regular food budget will apply. If it were me, I'd scale back on the tile or countertops I wanted, and apply that to a hotel budget.
Also, hold back a good chunk of the money, and work a penalty for delays into your contract. Otherwise, they may get your kitchen torn apart and then disappear for 2 days here and 3 days there for a few quick jobs that come up. (If they said "no" to those opportunities, someone else would get hired - so they just say "yes" to everyone and then figure it out.) They've got you cornered so your only defense is to hold on to their money and not pay up until everything is perfect, including cleaning up.
