I personally like the Breakers, but we generally go in late spring/early fall when the rates are low(er). But if you can get together with a group of paying adults, you can get a big room and split the cost. I personally feel that it is absolutely worth the money to be within walking distance to the park. There are 2 resort entrances, one goes to Magnum and the other to Wicked Twister. The rooms themselves are nothing special and pretty much the bare minimum, though I haven't stayed in a suite yet. A lot of the rooms have no elevator access and the cheapest rooms have the longest walk to the lobby it seems. Lake view rooms generally have a beautiful view. There are 2 outdoor pools and 1 indoor pool, a small arcade, a TGI Friday's and Perkins restaurants (both hugely expensive, of course). There's a convenience store and other small shops in the lobby. The check-in staff are very good and I've never had any sort of problem with anything at the Breakers except maybe low water pressure.
We once stayed in one of the cottages at Lighthouse Point. It was a beautiful view of the lake out the front door and pretty much next to Mean Streak in the back, but not really within walking distance to the park, although they have a shuttle bus service. The cottages and cabins are actually small mobile homes.
