Before they built the Hampton, I always stayed at Quality Inn. Once or twice the room was very musty from a wet carpet, so the window or roof must have leaked. They gave us a different room with no problem. I am not crazy about the restaurant there. As you mentioned it is tricky to get to the Quality Inn. You need to look for the right hand exit immediately after the toll booths, and then continue along the industrial park road with lots of large speed bumps. The sign is kind of dirty and faded. The place needs a little updating. That is why I wrote that the Hampton does not have much competition.
They are the same peolle that built and own the Intercontinental in SD.
The Hampton does not have a hotel shuttle, but there is usually a cab driver sitting there, and he charges about $15 US to take you to the airport.
That could be due to the sindicato that doesn’t allows things like UBER to reach the terminal (in theory.)
As far as a hotel within walking distance, I am not sure how much closer you can build something to the airport, but arriving in the hot summer or in the middle of a rainstorm would not be a very fun walk with one or two carry-ons or luggage.
The hotel will be built within the property of Las Américas because Vinci Airport or AERODOM is one of the owners/investors of this new hotel. I don’t think a hotel tower could be built on top of the current terminal, but in theory a new hotel tower could be added on top of the new to-be-built terminal or build a new hotel tower between the old (current) and the new terminal with closed pedestrian bridges connecting the hotel with both terminals (similar to the new pedestrian bridge built between the old tower and the new tower in the HOMS in Santiago.)
The Orlando International Airport is an example that a hotel can be built on top of the terminal, though I think that was part of the original plans when the airport was built. At least I have been numerous times at the Orlando Airport since the 1990’s and that hotel (was a Hyatt, could still be that brand) was already there the first time I went.
That would actually allow hotel guests to go down to the terminal and catch their flight without ever stepping outside. Same with airline tripulations in case they are based elsewhere and for whatever readon the flight was cancelled for that day. I guss in AILA this is mostly due to the weather elsewhere such as NYC during a snow storm.
