To be honest the Grand is just about grand, if you'll excuse the pun. The Abbeygate is central but a basic 3 star. Meadowlands is very nice, about 1/2 a mile from the town centre, but has no leisure facilities. The Brandon is OK, 4 star I think but in reality a good 3 star, it is more or less in the centre of town and has leisure facilities. The other option is Manor West, a new hotel which is 4 star and has leisure facilities. It is about a mile from the town centre but is beside the main shopping centre.
For a meal out try Restaurant David Norris, by far the best place to eat in Tralee.
I hope you enjoy your stay.
