corbett tiger reserve

I am trying planning a trip to the corbett park. My LP is rather out of date and there are so many hotels on the web site i found it confusing.
what we need is :- to get from Delhi to the park. Stay in a lovely hotel/guest house/cottage. Go on elephant and or jeep safari. Chill out with a cold beer.
We are not really on a budget but dont want to pay 5* prices.
I am also a bit concerned with getting ripped off along the way , regarding park fees, safaris, and the endless ferangi stealth tax! Are there cottages etc in the park or is a drive away? Also what will the weather be like at the end of March?
Any help and suggestions will be really appreciated.
happy travelling.
