Depends on whether or not you think people would use them. If you think your local guests might still want to use a room so that they don't have to drive home drunk, then block some. If not, then give your OOT guests some hotel options in Westbury/Jericho/Hicksville.
Hmmm... you can only be the judge of that. We are staying at the Hilton Garden Inn and I actually have more local people (mostly friends) staying. We live in Brooklyn and don't want to drive back so we liked the complimentary shuttle to and from the hall through the Hilton.
We are using La Quinta and they provide free shuttle to and back from JT. There is also Hilton Garden Inn that also provides free shuttle to and back from JT, but I had a terrible experience with them and ended up switching to La Quinta. Getting in touch with Nadine was a nightmare and I was not happy with their customer service.
My wedding was at JT and we used Melville Marriott bc we live in Massapequa...it worked out great! BEAUTIFUL hotel and the most comfortable beds you will EVER sleep on! You can also try the Marriott in Uniondale.
