We stayed at Westgate Lakes in January. Be careful where they assign you. We were in an older (they say 5 years old-it looked older) building with a playground and kids' pool right outside our door -first floor. This may be where you want to be. The 2 bedroom units were large and would be great for 5 people.
We only had a studio which looked nothing like the ones they show on the tour in a new section. It was small with no privacy for the whirlpool tub. There were no tables, not even end or coffee tables and the snackbar was too small. The sink and refrigerator were too small and overall everything was somewhat worn. We had no stove or washer/dryer. Make sure you bring your own shampoo etc and if you're driving, your own sheets and towels-they smelled and the sheets were way too small for the King bed. They did come 2 days before we left-5 days after we checked in- and changed the sheets-ever smaller than the first time and changed the towels after we had washed them in a public machine. They threw out the soap I had brought. I didn't think they would change anything so close to leaving.
We stayed at a cheaper rate as long as we did the presentation which also took us over 3 hours, not 90 minutes. They are very pushy but it was worth the discount price and free tickets if you know how to say no to a purchase. Maybe if they had put us in a better room, we might have considered it. It is a convienient location to Universal, Seaworld, and WDW as well as the new outlet malls and the shrine if you need to attend Mass. You're also closer to the airport than some places. However, you cannot walk anywhere-you are blocked by 4 for anything on International Drive so make sure you have a car.
You should enjoy it there if you are prepared to ask for an updated room, and say no to the presentation if you don't want to buy. With all the deals you learn about on these boards, why would anyone purchase here?
