there is a good hotel near the highway that i know off but i dont know the rates here - will find them out....and is your budget of 2200/- per head or for both ? :O
eating shouldnt be a problem cause every look-and-corner has hotels which can fill stomach of 2 people in 100 buks easily. (talking of good food , unless u want to cherish mumbai ka vada pav! p.s u have to try that

)
edit : just inquired : 3000 + tax for a double room.
if u would wish to travel by train in the mornings - off peak on that route - station is 1 min away from the hotel
since u would return in the evening in the opposite direction that would be off peak for u too , thats something u are lucky at.
train tickets would cost you - rs. 8 for a return ticket per head
and then rickshaw from goregaon like i said and the same route back.
direct to venue in rickshaw ( and the rick guy cannot take u for a ride cause its on the highway itself

) ~30-40 buks
prices should be really cheaper in goregaon area since its away from the airport too.
goregoan people! wake up!!!
