Cartgate, I kind of noticed that other KP parents & Mids are too busy to take time out from celebrating to elaborate so I'll add my two cents.

To & from airports and while out & about Great Neck, Bayside & surrounding areas, I highly recommend Manny car service-516.487.5466 over the local Friendly's Taxi. Mannys is around the same cost as a "taxi service" but reliable, clean, and with up kept vehicles. Sorry Friendly's. Ya'll stuck me twice & my kid more than that so I'm not a fan. Manny's was always great. Used them for airport to hotel rides to Academy to hotel rides. I hate to quote their prices as its been one year since I've used them last and prices might have changed. Please do call in advance. I'm hoping others can weigh in further with their opinions.
I'm not a travel writer but I play one on your forum.

In trying to answer what I see going on both here & in some private inquiries, I hope to add this additional information. First hint: RESERVE EARLY! This is for
ALL KP functions: INDOC, Parents' Week-end, sporting events & graduation.
I can't write as to the hotels listed but can give a small view into the hotels I'd used while visiting my Mid: The hotels in and around Great Neck are not 5 star diamond hotels. Keep in mind that you are only going to sleep there, not vacation like at a resort. They all have been renovated and renovated and re-renovated. The Andrew is where most would recommend to stay if you wanted to walk across the street to jump the Long Island Rail Road to go into the city. The bus is convenient to KP as well. Their rates for INDOC look to run about $180 per evening. They have been known to knock off about 10 bucks a night for KP parents so do call to inquire. I'm not a breakfast person but they do include the usual suspects. Clean rooms but very small. Spent two visits there with the most recent being 09's graduation. Hotel staff was pretty awesome. They do double their rates for graduation week as usually the US Open is in town so pay attention '11 Grad parents as you need to book there by January in order to avoid the price gouge. Everything you need is within walking distance.
Bayside is a pleasant place to stay as well. Good places to dine in the evenings. The Adria is actually a Ramada Inn. It runs about $135. per night at this moment. We stayed there during INDOC drop off and met several parents & plebes-to-be. Parking garage was a pain but then walk across the street to either two fast food places for a milk shake & life will be good again. The rooms are the usual hotel rooms but clean and comfortable for what you would need them for. SLEEP. The lobby is a little scary but whatcha gonna do? The hotel staff was very helpful and friendly. Easy drive into Great Neck,the Academy or Manny's will pick ya up.
Advertising Disclaimer: Might I also suggest Dunkin Donuts coffee. Three at a go round to keep up with your soon to be Mid. And while in Great Neck, stop at Deli on the Green. OH YUM. I want one in my kitchen 24/7. I have to add a trip to Lazar's Chocolates after. A true old fashioned Mom & Pop candy shoppe that hand delivers to KP. Tell them you want the "South Carolina Jamzmom Discount Special". They owe me.

I'M TEASING! Seriously, they are awesome folks who can make your kid smile when you can't.
Hope some or any of this helps to the new comers. Please do ask any question. We've got some great KP people with the best advice here. Good luck & carry on.
