My advice to you is to reconsider your choice of Amerisuites. I stayed at the Amerisuites Universal last August and it was awful!
First of all, calling these rooms suites is a crime:what you actually get is a standard sized hotel room with 2 double (NOT queen) beds shoved to within a foot of each other so that a partition can be built to house a loveseat, chair, desk, and small counter. The counter holds a SMALL fridge(2 liter soda bottles will not fit well), very small micro, and a coffee maker.
The TV is positioned on a swivel base so that you can watch it in the "bedroom" or crane your neck to watch around the partition in the seating area.
It was myself and 3 kids under 12 and we were VERY cramped. We paid 69 per night, and I would have been able to deal with the cramped quarters if it had not been for all the other problems...
the 1st night we were there a false alarm at 3 am and we had to evacuate the building,
the second night our toilet backed up and we waited over 2 hours for a plunger, the fellow that brought it expected us to fix it ourselves and when I insisted he do it, he left a wet mess in the bathroom.
the third night we came back from the parks at 10 pm to find our door had been left propped wide open all day by the housekeeping staff.
as we packed to leave onthe 5th day I checked behind the loveseat to see if the kids had dropped anything there and found an old empty vodka bottle which I presented to the front desk as I checked out. They took the last night off my bill... gee thanks.
The only positive things there was nice pool & a decent continental breakfast, but no other food service on the premises.
In contrast I stayed at the Holiday Inn right next door for my next trip. For 89 per night we got a real suite with 2 large rooms, full kitchen & dining area, 2 TVs, 2 vanities, 2 queen beds in the bedroom, and a queen size convertible in the living room. We were 6 people for that trip and very comfy. They had a TGIFriday's on site which offered a nice hot breakfast buffet and terrific room service.
I have never done the house rental thing nd I have heard good and bad stoories about it, but it sounds like it might work for you since you have the time to research it.
Good luck!
