When my agent booked us, it was originally gonna be 4 of us, not 5. We asked the same thing and the resort told him that there is no break in cost if you put 4 to a room. You will pay the same amount as though you had 2 rooms. So, it's possible, but seems like a waste. We put 3 to a room because the single supplement wasn't worth it.
I agree , there really isnt much savings once you get to 3 and 4 and 5 people. 3 in a room makes sense, cuz a single room is expensive for one person, but if you have 4 your better off going 2&2.. plus you may not kill each other that way , considering with 4 people in one of those rooms for a week or more. might be a tad small
Thanks for the info! As we book and the date gets closer I am sure I'll have lots of newbie questions. These boards are awesome!
