I'm planning a trip for the exact same week - 4/4/15 - 4/11/15. The problem in getting a really cheap rate is that it's during spring break. Easter is Sunday, April 5 and hotel prices seem to be way up from other times of the year. We are also going with a party of five (DH, myself, our two teen boys, and my sister). Most hotels I've checked have a maximum occupancy based on the number of beds. You would not be allowed to have an extra person in a room with 2 doubles or queens. When you look at the larger rooms that include sofa beds for a 5th person, the price really goes up! Also, New York City hotels seem to have different bed configurations than we're used to. The rooms are on the smaller side, and the least expensive ones have one double, one queen or two twins. When hotels advertise their lowest price, it's for those rooms.
Everyone in our party really wants a bed as opposed to a sofa, since we'll be there for seven nights. And since we really want two bathrooms, we've decided it's best to book two rooms. DH and I will have one teen boy, the other will be in my sister's room. I had originally booked two rooms, each with two queens, at the La Quinta Manhattan for $232/night. After reading some of the reviews, I decided against it. We also looked closely at the Homewood Suites, which is a newer hotel. Trip Advisor reviews frequently mentioned paper-thin walls, small rooms (even worse if you pull out the sofa), and a very small breakfast area that can't accommodate a full hotel. That didn't sound like much fun.
Right now, we are booked in two junior suites at the Affinia Shelburne, each with two queen beds and a small kitchen area. The rate is $311 per room (yikes!), but this is a cross-country trip for us and not likely to be repeated anytime soon. We don't want to be stuck in a cheap, dirty hotel. My sister stayed at the Dumont, their sister hotel, a few years ago and was happy with it. We also want to be near Grand Central, so we looked mostly at midtown hotels.
I'm going to continue checking rates as we get closer to our trip. I don't really have high hopes for finding anything really inexpensive that's worth booking.
